An Islingtonism, as defined by Totenbuch Christ, is something which is funny only because is has been said so many times. As he puts it, "It is not what is said, but how often." Repetition breeds humour. Islingtonisms can more widely be considered to be any form of inappropriate, overused non-humour which causes resentful laughter.

What Do You Think You Are, Some Sort Of Fucking Messiah? -- Invented by Totenbuch Christ. Used when someone tries to lead a group or when one compliments one's self.
What Are You, Some Kind Of Faggot? -- Invented by Totenbuch Christ. Said to anyone who disagrees with the majority, or with the accuser.
Your Mother -- Various claims of origin. Originally a reply to "What are you doing?" (or any variant thereof), it later progressed to the status it enjoys today of an all purpose reply. ("What time is it?" "Your mother"; "How are you?" "Your mother".) The most used Islingtonism.
Tomorrow's Saturday! (insane laughter) -- Invented by Milky, Golden Rodent and Finn, as a means of mocking those who find humour in the simple mistake of forgetting that Saturday is a day off school. Main use is "See you at school tomorrow?" "Tomorrow's Saturday!" (at this point anyone within earshot breaks out into insane laughter).
Got NE Warez? -- Invented by pirates and Asphalt Bastard. Includes variations "Hey man, I got warez" (defensive comment), "You don't have any warez" (insult) and "Does your mother have any warez?" (mother-based comment).

Honey, Honeywagon -- Invented by the Fresh Prince, popularized by Totenbuch Christ. A Honeywagon is a cool car, preferably with T-roofs. Honeys are girls. When driving in a Honeywagon, one yells: "Woo! HONEYS!!" even if there are none in sight.
Two (giggle), Silly! (giggle) -- Invented by Creeping Face, as his impression of that type of girl. "Two" is the standard number, but should be accompanied by a giggle. "Silly" is the all purpose means of addressing people, also accompanied by a giggle.
