b-tomb
It's when you put random stuff on your boner, and it's so ridiculous that it makes your whole house laugh.
I put my mom's coffee mug, my dad's tie, and my brother's leg on my boner. The whole house heard it crash.
My sister tried to balance her homework, her cat, and a bag of chips on her boner. The cat ran away and the chips exploded.
I did a b-tomb with my phone, my sister's headphones, and my mom's old hat. It was like a crazy science experiment.
