Cassieing

shamelessly checking out a dude's really ripped sexy biceps; admiring a hot guy's hot arms, usually involves touching them sensually or staring at them like the piece of meat that they sometimes are. lol

girl: do you lift a lot? your arms look delicious...
guy: yeah, you are totally Cassieing me right now

girl 1: omg did you see Mark's arms at the gym today?!?
girl 2: you know i did, even with the farmer's tan i was still Cassieing so hard
