Clitboners, or also known as CB's, are when a girls clit becomes hard and aroused when she is turned on. Also can be used to describe dudes who are acting like faggots usually the ones with a tight Polo shirt on and a fake tan trying to act hard.
"Dude, we've got a bunch of clit boners in here."
"I bet that bitch has a fucking clit boner right now."
"If a dude can get a boner then chicks can get clit boners."
"That skirt is so short that I bet if she gets horny her clit boner would prop her skirt up."
