When you shart after standing up.
I was playing Garry's Mod, and when I stood up I Forceghosted.
When you're a big hoe and steal other peoples friends by e-flirting with them.
'My friend poscoe met this ugly hoe and Vickied me.'
When your friend leaves you for a girl
I was playing Counter-Strike last night, and my friend met some girl, after a while he Poscoed my team.
