in my pants 

A game where people add or use the phrase "In my pants" as a supplement or to replace part of a sentence. This should not be done in a conversational group of sentences, because it is just plain stupid. You should use movie or song names, common phrases, lines from songs, or well known quotes. The object is only to make each other laugh. Be creative. Can also be done with the words "between the sheets".

A: "Spice up your life" in my pants
B: Haha! "Welcome to the jungle" in my pants.
C: How about... "10 things I hate about you" in my pants.

In My Pants 

A vocal game invented by... er, sorry. I sort of forgot. But its played by ending everthing you say with the words "In My Pants". When a person playing the game fails to do this, said person is then punished physically and severely (ex.- caning, ass-whupin', socked in da' gut, etc). The game ends when the time limit (if any is agreed upon) is over. ... Or just when everone gets tired of it.

Kid #1: Hey, how's it going "In My Pants"?
Kid #2: Pretty shitty "In My Pants".
Kid #3: That sucks "In My Pants".
Kid #4: ... This is pretty stupid.
Kid #1-3: GET HIM!!!
