Infamous Mr.T quote.

a half-assed laugh that you give as a reaction to a stupid story or comment, pity laughs are usually used when the story or comment is ment to be funny but really isn't

When, after a period of one-sided sexual attraction, the uninterested person feels so sorry for the unattractive pursuer that they agree to kiss.

This happens because either (a) they don't think the dweeb can take anymore rejection, or (b) they think it might pump up the poor sap's self-esteem.

The one Oreo you give away to someone so you don't feel self remorse for eating the whole box.

A way of experiencing grief, in which you spend your time feeling sorry for yourself and whining endlessly about how crappy your life is.
Pity parties can be just for one or for many people, such as maybe your friends and close people, who will try to comfort you or just be there for you while you keep asking yourself what did you do to deserve whatever it is that made you so sad in the first place
Pity Parties require the proper outfit, which is usually pajamas cause you dont get all dressed up during those feeling-sorry-for-myself moments. Also you should have no make up on or just the one from the night before; hair undone as well.
It also involves tissues, comfort food such as ice cream; chocolate; potato chips; cookies; cake; and candy. Low fat food is banned
Alcohol might or might not be allowed (if alcohol makes you go wild, no alcohol should be brought to the pity party in that case since the point is not exactly to have fun). The purpose of a Pity Party is to dumpt the pity
Music is also very important at pity parties, including songs like "One is the Loneliest Number", "All by Myself" and any other song that makes you feel like throwing yourself from the nearest cliff
Pity parties usually end after you are done whining or if someone breaks it up. This will usually be a cynical loved one who will not let you drown in self pity and will take you either to have the best time ever, drinking and partying or will just make you crawl out of bed by making you see how pathetic you look and how you should cut the whining and just do something to make things better

When a guy comes too quickly during sex and the girl is left unsatisfied, it is common courtesy to offer to finish her off with the hands or mouth. It is also an act of pity if she was very close but the guy beat her to the finish line. Best undertaken without drawing attention to the fact that it is, in fact, out of pity.

Sitting on a pity potty is a more solitary exercise than going to a pity party, but both describe feeling sorry for one-self.
While sitting on the pity pot, the victim bemoans his or her own fate, usually only making comparisons with those more fortunate--those richer, smarter, funnier, sexier, and better looking. And in far less trouble!
"Oh, woe be me!" is a common thought, as is "Oh shit, oh damn!"
Any recovering addict spends a lot of time first sitting on the pity pot and will strongly resemble a baby or toddler at early toilet-training. When addicts finally start to work their twelve step program, they gradually learn how to accept responsibility for their own body functions and actions, do the right thing, and become productive members of society. At this point, the initial work is done, and the addict is able to get off the pot. Who flushes it, is irrelevant. At least the addict has stopped all that whining.
