I have never heard of it.

I guess he was trying to come onto you and say that you were rather good-looking without sounding too weird.

Or it may have been an insult if you take it another way. I don't know.

He told you that he was bi afterwards so he probably liked you then.

I think it means slightly or a little attractive. I think I've heard the term being used to apply to people who look attractive, but dress plainly.

But judging by your profile picture, I'd say you have good taste in clothing and appearance ^_^

Reasonably attractive means that you are okay, not the best looking, but not the ugliest either.

It means that you were not really his type but he still thinks are somewhat attractive. It's sort of a "cute but not by my standards" type of comment. It's a mix between compliment and insult.

Its a nice way of saying you look okay, not hot, not ugly.

it means that perhaps you won't scare the kiddies...
