Backseat Bullride

While having sex with a girl doggy-style, use one of your hands, and grab on to the opposite boob (left hand right boob, right hand left boob). Then, whisper in her ear, "Your sister likes it this way," and try to hang on for 10 seconds.

Man, I almost did a backseat bullride on my gf last night, I hung on for 9 seconds!

backspacer

When IMing with someone, you notice in the status bar that the person is typing, but after a minute only replies with LOL! This may be done because the typer starts a thought but doesn't want to get into it.

me: ...Minas Tirith is the castle at Gondor
drew: *yawn hehe
me: wha!?
drew...after typing for 2 full minutes: lol
me: Backspacer!
drew: bah!

Player 1: That's not really how it's done, but I'll allow it.
Player 2: Wait a minute! That's against rule 534 on page *flips open rulebook*
P1: I'M the DM here. Don't backseat dm me.
