b-tomb
When you put anything on your boner, no matter how random, and you're just hoping it doesn't fall off and hit you in the face.
I put my mom's old comb, my dad's shoes, and my sister's homework on my boner. It fell off and hit me in the face.
My brother tried to balance his entire sock drawer, his phone, and his dog on his boner. The dog ran away and the phone broke.
I did a b-tomb with my mom's coffee mug, my dad's belt, and my sister's hairbrush. It was a mess, but it was worth it.
