look up any word, like muddin:
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!
