★ Fantasy sports rum dum style · est. 2026 · commish-run

Fantasy worth showing up for.

Twelve friends. One ring. Daily contests where the only stakes are dignity, the only prize is a belt, and the trash talk is the actual product.

The gist

Three rules. No homework.

01

Pick one player

Every night, every manager picks one NBA player from tonight's slate. Lineups lock at the first tip-off.

02

Outscore everyone

Standard fantasy scoring. Highest single-player total wins the night. Tie goes to the louder trash talker.

03

Hoist the belt

Winner holds the belt. The site tracks belts, streaks, head-to-heads, and the moments your friends pretend never happened.
