What exactly does it mean if a guy's jaw drops when he looks at a girl?

[Anonymous]

I'm not sure what to think of it. This guy and I made eye contact and his jaw dropped quite a bit. I'm just curious if it means anything, and if it does, what does it mean?

Guys don't usually look at me like that so I am just curious.

It was probably a nervous reaction which means he probably likes you.
