A slightly more subtle way to refer to getting up in someone's genital area. Basically
"Can I get up in those jeans?" = "Can I tap that ass?"
"Tell me is there any more room for me...in those jeans?" -Ginuwine ("In Those Jeans")

"Yo guess what? I just did your sister in the ass."
"Shut up bitch, that girl makes Jessica Simpson look like a 2 dollar whore. Even Ginuwine couldn't get up in those jeans."

Hey Brad, are those bugle boy jeans you're wearing? Rawr!?!
