It means he's one of those bobble-head dolls and you should put him on the ledge of your car's rear window.
What else can it mean??
Yes he wants to have sex with you and is obvious
He has a crick in his neck and nodding helps it feel better.
it probably means he is very rude with his body language. and doesnt respect women very much, and it also means he does that to alot of women. it says alot if you ask me. but to a woman i guess it can also be flattering too. but i wouldnt take him seriously. just my opinion.
it means he is stripping you with his eyes
He's picturing you naked.
Tou mean the old elevator look?<br />
It means the guy is a jerk, and is too inept to even slightly hide it.
