dealing with tilt?

[mulebennett]

hi guys, i'm new to the forums here and very anxious to begin posting. well, i play in mostly home games and have lost a couple hundred playing online--but i am getting a little bit better at playing online, so i am playing more aggressively.

anyway, in my home game today i was playing with these kids that i live with and normally i have no problem with them but the one kid that i room with always puts me in a bad mood and i typically avoid playing with him because i often catch a bad beat and piddle away my money.

today he called my raise with Ks5s and i had Ac10c. so i bet after the flop comes Kd5d5h and he turns to me and says "well it might be an early night for me" and pushes all in, so i call and he flips over the boat.

it infuriated me because in a friendly game like this people do not normally talk smack to each other and we enjoy each other's company. i thought it was pretty unsportsmanlike..and i'm not the type to get angered by a check-raise or anything.

so my question to the members of this forum is, what puts you on tilt and how do you deal with it?
