Side B

Recycling the usage of your dirty undergarment by flipping it inside-out on it's "side B" which is supposedly cleaner than it's "side A". People who're lazy to do their laundry do this all the time.

"Dude isn't that the same Calvin Klein undies you were wearing yesterday when we went to the beach?"

"Don't worry man, it's on it's Side B"

"That's just gross dude..."

Side B

Way of saying Side B theology; essentially used by those who experience same-sex attraction (therefore are gay, lesbian or bi) who do not affirm the lifestyle choices but rather opt to follow traditional Christian values such as marriage only being between a man and a woman, and sex only being for such marriages.

Yeah, I'm gay but I'm Side B so not gonna marry a guy.

Bloc Side Soldiers (B.S.S.)

A Detroit graffiti crew from the mid-2010s that evolved into the Hyena Crips (83GC), a core clique of the 5 Point Nation Crip alliance. Originating on the city’s far Northwest Side near West Seven Mile and Five Points, B.S.S. was known for bold block-letter tags before shifting from graffiti to a loose street-crew identity as the Hyena Crips name took hold in the late 2010s.

“Before they were the Hyena Crips (83GC), they were Bloc Side Soldiers (B.S.S.), holding down Detroit’s Five Points neighborhood.” — Detroiter
