Brophilactic 

A friend who consistently interrupts or makes invalid your attempts to score with a female but is still your bro.

Johnny would have nailed that blonde chick if it wasn't for Charles rippin one in the car. What a brophilactic.

When your best friend takes off his condom and turns it inside out for you to use.

My roommate knocked on my door and asked if I had an extra dong bag, I said regetably I was still wearing my last soldier. But as a good mate, I turned that shit inside out and saved the day with a Brophylactic!
