to get rowdy, to drink aggressively, and to have an awesome time.
Note: while one usually uses the formal expression "hang out with beecher," one can also use mention "meeting up with beecher," or "saying hi to beecher" in order to use subtlety or to imply varying degrees of rowd.
"You don't have work tomorrow? Dude, we're definitely gonna hang out with beecher tonight!"
"I was just going to stop by to say hi to everyone, but I ended up hanging out with beecher and I didn't get home until 4am."
"you look pretty tired; were you chilling with beecher last night?"
