about guys

That's what guys do when they are either

a.) Squeezing out a fart
b.) Taking a dump in their pants

Both of these moves are great ways of letting a lady know your interested. In fact, I actually found my latest girlfriend by using this technique.

yeah, pretty much.

Depends on the head.

If he lowered his head and raised his eyebrows it means "Whoa - what is that?"
That can be a compliment or a dissing.

If he raised his head it means he is surprised at what he saw.

Ask your husband. I'm sure he'll be pleased to teach you more about men and their signals.

Ouch !
