look-back

When someone glances at you, looks away, then immediatedly looks back. Like a double take, but sexy.

"I got 2 look-backs from total hotties today"

"Dude that wasn't a look-back, she had something in her eye!"

y-back

Tank top worn by bodybuilders that has two straps in the front and comes together in the back as one strap making a Y appearance.

Travis has a sweet y-back, but Tyler definently fills it out better because he is more huge.
