A term used to describe the most ultimate form of trust that a man can ever bestow on another man.
Balltrust takes place when a guy trusts another guy SO MUCH that, if it came down to it, he would trust this man with his own testicles. This form of trust is very rare because a man is never as vulnerable as when his nuts are on the line.
1. (verb) Jake: Aww, did you leave that last beer for me?

2. (verb) Jake (after walking in on Pip bangin' Jake's girlfriend): But, dude! I BALLTRUSTED you!

3. (noun) Billy: You thought Pip was just helping her with homework?
Jake: Yeah.
Billy: Dude. That's a massive amount of BALLTRUST!
