sackstache

Testicular hair. Often a source of pride for Millennials unable to achieve a proper ironic mustache.

Hipster A: Bro, how are we supposed to get into this uber-popular "unknown" brunch establishment with that pathetic looking peach-fuzz on your upper lip?
Hipster B: No problem, my dark-skinned-friend, I am going to flash the hostess this mad sackstache I've been cultivating. She's going to be super impressed and we'll be sipping mimosas well into the evening.

shack

An unexpected sleepover at someone else's place. Sex may or may not happen. The term shacking does not apply to staying the night expectedly, when you have your own change of clothes and a toothbrush. A shack often involves borrowing or stealing the guy's clothes for the walk of shame the morning after, thus the term "shacker outfit."

"Yeah I shacked at his place last night after Paddy's."
"Nicole didn't come home last night, she shacked at Ryan's."

shack up with your girlfriend

what all teenage and young adult men ages 14-22 (or so) need to do if they want to avoid embarrassing pda moments.

Not only do our young men need to know what shack up with your girlfriend actually means, but they also need to learn what decorum is and not insult their parents' values.
