Cool boner bro 

A suitable way to articulate your lack of interest in a male after he forcibly thrusts his erection in the direction of your butthole whilst spooning with him; also an appropriate response to a photograph of a boner sent via text or E-mail.

An adaption of the infamous cool story bro

Chess: Yeah so I was totes spooning with Seth last night, and he kept pushing his boner into my ass. I was like cool boner bro.

Anke: Dude, I said that when Jack told me he was hard.

When your cocked and loaded, condom on, about to bang your bros ex girl, your boner thinks more clearly then you and says no, and retreats like the British in any war ever.

Bro #1 walks out of room in the morning, " bro I almost banged (insert bro) ex last night, she is super dumb and hot,but I couldnt do it." Bro #2" bro boner dude."
