See if you can use someone else's.

Realizing you can't hold it anymore, you dash out of the room, hoping to make this a quick trip. The rest of the people on your floor are, for the most part, stuck-up pricks who wouldn't as much share a roll of toilet paper, let alone their whole bathroom. So you decide to go to the one room with whose residents you get along with. Hurriedly you run across the hall and knock on the door. After several excruciating moments, the door swings open and your are greeted by a plume of smoke. You began to hack wildly, your lungs not used to the thick smoke attributed to pot.

At the doorway, a lanky young man with dreadlocks and full beard greets you, his eyes glazed over. Through the white smoke, you see another teenager sitting in a beanbag chair, holding a rather ornate bong. Tie-dye banners and glow-in-the-dark posters lined the walls.

"Oh hey, Jack-man." The guy at the door says slowly.

"Hey Scott. Hey Dirk." You say quickly.

"What's up, dude?" Dirk, the teen in the beanbag chair spoke up. "Looking for a hacky-sack rematch?"

"Not right now." You shake your head. "Listen, I need to use your bathroom."

"Why?" Scott asked, drawing out each syllable as he spoke. "Yours on the fritz again?"

"No, Melody is in there." You shake your head. "I don't want to disturb her."

"Right on, right on." Scott nods. "Gotta give women their space, right?" He motioned for you to come in. "My toilet is your toilet, dude."

"Thanks, Scott." You say quickly, but he stops you by grabbing your arm.

"But you gotta pass the test first."

"Test?" You ask wearily.

"Of course, Jack-man." Dirk said. "We can't just let anyone sit on our most holy throne. You gotta prove your worth first."

"I've used your bathroom before!" You exclaim, but Scott doesn't let go.

"It's totally not a big deal." He said. "Just a quick initiation and you're good to go."

"Fine, fine." You say quickly, not in a mood to argue. "What is it I have to do?" Scott grins and pulls out a beer bong.

"Funneling, man." He says. "Gotta down two beers."

"Oh jeez." You roll your eyes. You should have guessed as much. The whole idea is rather stupid, but the idea of rushing liquids is only making it harder to hold it in. You don't have much time left if you want to find an alternate solution. You sigh as your window of opportunity closes.
