A man who thinks he’s fuckin chill, but actually is a pussy fuck. Kids that think they "trap" but are actually those dudes drinking mikes hard and dancing to mainstream alternative music. Those dudes who consistently say things like “Squaa” or “Dank!”. In addition, any fuck that regularly talks about turning up or how he "got so fucked up" is a classic Boner in the Frat.

Drinking mikes hard=BITF
Drinking only beer=BITF
Ordering chocolate milk at a local food establishment=BITF
Duff=BITF
