Bobby Shmurda will be stickin' to music because basketball ain't it ... the Brooklyn rapper botched an easy alley-oop dunk -- and it was hilarious!
The epic fail was caught on video ... the 27-year-old went to the famed CoolKicks store in Los Angeles for a sneaker shopping sesh on Wednesday.
There's a basketball hoop in the store ... so when Bobby arrived, store owner Adeel Shams -- aka Champagepaki -- placed a $1,500 store credit wager on whether Shmurda could beat him one-on-one.
