What does sexual tension feel like between total strangers?

Can you have sexual tension with a stranger? What does it look like? What does it feel like? Want answers from guys especially. ;)

Yeah it can happen. There was a time when a girl on a streetcar was looking at me in the eyes really intensely. She would look away, blush, and fiddle with her fingers whenever I looked back and catch her looking.

DEFINITE sexual tension there.
