sidesheeted 

Sleeping with somebody instead of sicking to the plan.

Ralph: I'm really sorry Zoe and I didn't make it to your birthday Fred, we got sidesheeted.

Fred: Thats cool man, Zoe is hella banging, I'd hit that instead of going to a party any day.

Ralph: Sweet I'll buy you a beer later

Fred: Nahh its cool, you work late on Thursdays....
