runamuck 

when you get engaged to a girl, but decide to take drugs and sleep with any other girl who is available just because it is a special occasion..ie an 18th bday.

rachael:what's this i hear about you cheating on me at that party?

rachael:..........what do you mean i wasn't around???? i was in the room next door.......

Runamuk 

Saying good-looking bye to any and all ambitions, morals or standards. Going out usually at night with little to no people and reaping havoc on society as a whole

Let's go runamuk tonight , I haven't been out and about in forever. Been dying to get into some trouble

runnamuck 

to leave the bar after midnight drunk or buzzed and drive home. and to try to get in a race with any and every car on the road at the time. to purposely provoke the highway patrol into chasing you. all just for the excitement.

well its 3:00 a.m and i hear that v8 powered s10 coming with sirens screaming. that fucker must be on a runnamuck again.
