boner sniffer 

A jealous biiotch who insists on smelling her man's crotch when he comes home after a "guys night out."

That skank Kayla is a boner sniffer! Every time Tony comes home after hanging out with the guys, she tells him to drop trou so she can sniff his crotch for traces of another woman's cootchie sauce!
