brown snake peek-a-boo 

The result of excessive drinking and debautchalism, a brown snake peek-a-boo is that poop that everyone periodically has (even girls that think they're "hot") that refuses to play nice. Instead, it comes out part way, then retreats, then comes out part way, then retreats...and so on and so forth. Fags (i.e. Jonesy) love the brown snake peek-a-boo.

Mike: Jonesy - your mom is hot.
Jonesy: I just had the best brown snake peek-a-boo!

Ukrainian peek-a-boo 

Classic scam mastered by Frank Gallagher from Shameless. Involves jumping out in front of a moving car as your partner distracts them, then shaking them down for cash. Also the slang term for the surprise Trump got when several respected diplomats jumped out and testified against him regarding his extortion campaign in Ukraine.

Definition 1:

Frank: Bro, I'm short on cash. Let's do a Ukrainian peek-a-boo!
Frank's creepy friend: Nah, man, people don't carry cash anymore; it's not worth it.

Definition 2:

Rob: Dude, did you see what happened with Trump!?
Tom: Yeah man, he got a serious Ukrainian peek-a-boo!
