youtuber sinjin drowning

i seriously dont understand where the username sinjin drowning came from.. LIKE THE CHARACTER FROM VICTORIOUS? he wanted him to DROWN??!?! i dont get it.. am i slow???

also ive been binge watching their videos recently and i cant get over the fact that no matter how many i watch i cannot remember what ive watched... like the tdi videos mess me up so bad cause i never have an idea on what ive already watched.. ive probably rewatched their videos so much now because of it.. okay end of rant

ps couldnt find  a youtube catgeory so it gets movies and tv
