One that shares the unique sexual preference of Fall Out Boy bassist Pete Wentz, i.e., one that enjoys kissing of varying degrees of passion with members of the same sex, but won't actually sleep with them. Often gets off more on the nonconformity of the act than their actual partner.

In layman's terms, first base is the end of the line.
"Dude, your roommate hasn't called me back since we kissed. What's going on?"
"His über-Catholic parents from the Bible Belt were visiting that weekend. You probably won't get a call until he gets another opportunity to piss them off."
"Aw, man, I had no idea he was a wentzsexual..."
