Tongue of the slip

There may be many a 'slip between the tongue and the lip' sorry “between the cup and the lip”, but all are not same.

For example there area few categorizations like

1. Spoonerism

2. Malapropism

3. Freudian Slip

1.Spoonerism:

MEANING: The transposition of (usually) the initial sounds of words producing a humorous result. For example:
"It is now kisstomary to cuss the bride." (Spooner while officiating at a wedding)
"Is the bean dizzy?" (Spooner questioning the secretary of his dean)

2. Malapropism

MEANING: The humorous misuse of a word by confusing it with a similar-sounding word.
For example, "pineapple of perfection" for "pinnacle of perfection".

Usage: "Mayor Thomas Menino is sometimes made fun of for his malapropisms; He once said the city's parking shortage was 'an Alcatraz^* around my neck' (instead of Albatross around my neck)."

3. Freudian Slip:

MEANING: An error that reveals someone's subconscious mind.
For example, "I wish you were her" instead of "I wish you were here."

USAGE:

"The Freudian slip is invoked to explain some strange and embarrassing behavior. 'Nice to beat you,' smiles a woman when she meets the ex-girlfriend of her husband."

• "Normal speech contains a large number of such slips, though these mostly pass unnoticed. The errors fall into patterns, and it is possible to draw conclusions from them about the underlying mechanisms involved. They can be divided into (1) Selection errors, where a wrong item has been chosen, usually a lexical item, as with tomorrow instead of today in That's all for tomorrow. (2) Assemblage errors, where the correct items have been selected, but they have been assembled in the wrong order, as in holed and sealed for 'soled and healed.'"
  (Jean Aitchison, "Slip of the Tongue." The Oxford Companion to the English Language, 1992)
  

• "Most everyday slips of the tongue . . . are often simply the result of a sound being carried over from one word to the next, as in black bloxes (for 'black boxes'), or a sound used in one word in anticipation of its occurrence in the next word, as in noman numeral (for 'roman numeral'), or a tup of tea ('cup'), or the most highly played player ('paid'). The last example is close to the reversal type of slip, illustrated by shu flots, which may not make you beel fetter if you're suffering from a stick neff, and it's always better to loop before you leak. The last two examples involve the interchange of word-final sounds and are much less common than word-initial slips."
  (George Yule, The Study of Language. Cambridge Univ. Press, 2010)
  

• "[I]t is possible to make predictions about the form tongue slips are likely to take when they occur. Given the intended sentence 'The car missed the bike / but hit the wall' (where / marks an intonation/rhythm boundary, and the strongly stressed words are italicized), the likely slips are going to include bar for car or wit for hit. Most unlikely would be har for car (showing the influence of a less prominent word in the second tone unit) or lit for hit (showing a final consonant replacing an initial one)."
  (David Crystal, The Cambridge Encyclopedia of Language, 3rd ed. Cambridge Univ. Press, 2010
  

• "If a slip of the tongue that turns what the speaker intended to say into its opposite is made by one of the adversaries in a serious, argument it immediately puts him at a disadvantage, and his opponent seldom wastes any time in exploiting the advantage for his own ends."
  (Sigmund Freud, The Psychopathology of Everyday Life (1901), trans. by Anthea Bell. Penguin, 2002)
