bloody brain

When you squeeze your testicles so hard till it cuts off their circulation, it looks like a bloody brain.

I sent a picture of my "bloodybrain" to my girlfriend.

I got my girl so mad, she grabbed my nuts so hard and ended up giving me a bloody brain..

Jalapeño Bloodtrain

The act of stuffing as many jalapeños into a woman's vagina during her menstrual cycle.

The spices of the jalapeños help clot the blood and relieve bloating.

My cramping hurt so bad until I got jalapeño bloodtrained. My mom is great!
