to entertain the advances of an unattractive, beastly woman, usually at a bar or club. Often influenced by the later hours of the night when
beer goggles are
in full effect. Also usually followed by a buddy coming in to save you by whatever means necessary. The phrase is rooted in a popular national
Beef Jerky commercial.
"Look at
Brent over there at the bar! He's
messin with
sasquatch! somebody go save him!"
OR
"Dude, who was that hideous girl you were talking to last night?"
"I don't know man, whenever I drink to much I always end up messin' with sasquatch"
