An adjective applied to Yuppo DiPuppo, the astoundingly multi-talented superhero Italian-American dog, because he can easily travel faster than the speed of sound.
Yuppo, being yuppersonic, can travel from Seaside to Soledad and back in under three seconds, so if you’re at work and you forgot something important at home, that fabulous little supercanine can save your day!
Any period of time where you and your friends go out without initial purpose or expectations. Usually in the early hours of the morning or late at night, side quests last as long as everyone is still out away from their home, dorm, or common meeting space. Side quests usually happen after a "main quest," scheduled hang out or party and usually feature less people than the original main quest.
"I'm bored but idk what to do... wanna just go out?"
"Hell yeah man let's go on a sidequest!"
