Hey man, sorry for being so random ......saw this happen and just wanted another straight dudes opinion...

Say ur at a party and u notice this really hot girl check u out...as u are about to go and talk to her, some guy that u dont know who is really nerdy/wimpy starts talking to her and he looks really nervous....what would u do (and the wimp is like 5 years older than u but u knew u were bigger/more jacked)??
