He's hot but he's a player so you definatley don't want to date him... he's really a great friend though, super funny!
Girl 1: What would you say if Seamus asked you out?

Girl 2: Yes, of course! He is soo hot!!

Girl 1: Really? Have you even met him? He's a total player!

Girl 2: So, I would still say yes... it's not like I'll be surprised if he cheats on me! I'll see it coming.

A carnivorous marine animal, similar in appearance to its land-based cousin the emu, though with brownish scales instead of feathers. Lives on krill, rainbow trout and unwary swimmers.
Kevin was warned not to go in the water that day, but he didn't listen. When he didn't return, his girlfriend assumed he had been eaten by a seamu.
