What do girls mean when they say "nice legs" to a boy?

She's admiring the chicken drumsticks you're holding?

It means that your legs are nice and that they want to talk to you.

Its code for drugs.
Legs - pins, as in pins and 'needles'. They wanted to bang (up drugs). And then have sex.

It 'probably' means that you have nice legs. Just a presumption.

It means you have nice legs.

Lol. I don't know what girls mean when they say that even though I'm a girl.

You probably have chiseled manly legs..at least that's what I think of when I think of boys having nice legs. It is a rather strange compliment though! Was the girl someone who has always seen you in pants, and then upon seeing you in shorts, decided to comment on your beautiful hidden legs? Or was it a stranger. Hmmmm

Do you have muscular legs like a rugby player?
