Bobby Shmurda's Hat refers to the grey and blue New York Knicks hat worn by American rapper and recording artist Bobby Shmurda in the music video for his song "Hot N*gga." In the video, Shmurda removes the hat and tosses it over his shoulder and out of the frame. The move inspired a series of memes that joke about what happened to the hat.
A trainer was Shamurdered by one of the whales at Orlando's Sea World in February of 2010, prompting the San Diego location to temporarily cancel their Shamu show.
Getting Shmurda'd is when a musician gets arrested for dropping music with lyrics describing in detail real crimes they have committed (or plan to), to the point where it's an official confession of guilt to the authorities; popularized (unfortunately) in Early 2015 when artist Bobby Shmurda was arrested for "conspiracy to commit murder, weapons possession and reckless endangerment" fron his song "Hot N*gga"
