When a boyfriend hangs out with his friends way too much and all of the estrogen that his girlfriend has spent years showering him in starts to drain out of his body and a mass amount of testosterone takes over and he forgets about his girlfriend and does stupid man stuff with a bunch of smelly digusting meathead men, like drink beer, and smash beer cans on their heads, and measure thier weiners with each other and whatever else they do when they all get together.
"I knew my boyfriend was in man mode when he forgot about me for a week straight and spent every night with his friends."
