1. Better than fuckable
. Used to describe someone who is hot enough that you would date them. Can include someone who is only decently good looking, but has a great personality.
2. Someone who you actually like, as opposed to fuckable, which is purely sexual. A datable guy or girl is someone you enjoy talking to and would ALSO like to fuck.
John: I was talking to Shannon last night. Damn, that girl is hot.
Eric: Woah, woah, woah. Do you mean fuckable hot or dateable hot?
