Joel is such a ninja nerd, he acts normal but we know he's a huge geek deep down.

ninja farts

Silent, butt supremely smelly flatulence.

I love to release my ninja farts when I am standing on the diving board before a dive. It really fucks up the next competitor.

I also love to release my ninja farts while getting my salad tossed by a male prostitute.
