Gettin' tight

When a dude likes a chick, and his pants start "gettin' tight" about it.

"Hi Honey, how was your day at work?"
"Fine, beh-beh; the new girl was looking especially hot & fine today... She's lost a ton of weight, too!"
"WHAT?! Hey, asshole! I don't need to be hearin' you talk about how you're all 'gettin' tight' over OTHER WOMEN at your work."
"Oh, right.... Sorry."
