The act of partaking in platonic activites with a member of the opposite sex which, while appearing innocent on the surface, may be construed as inappropriate by a significant other. Pseudo-dating often involves mild flirtation and may progress to actual "dating" down the road.
My boyfriend gets very uncomfortable when I go on pseudo-dates with my handsome coworker.
I stopped pseudo-dating after we became serious because I wouldn't want him to do it to me.
"THAT" guy - you know the one... 20-something yuppie-in-training, lives with old college buddies in a messy apartment, never has toilet paper in the bathroom; loves life, beer, pizza, and hot 20-something girls although is hesitant to commit.
"... yeah, we met last weekend for drinks - he was as cute as I remember - but he's TOTALLY 20-Something-Guy!"
"He's still in 20-something-guy mode, but I'm hopeful he'll grow out of that by the time he's 30."
