An ignorant homosexual who often tries to troll people online, to no avail. If you see a River J, your best option is to ignore them and/or get away as quickly as possible.
I saw a River J last night, he was trying to troll on NextGenUpdate.
It is a gay guys name on nextgenupdate.
He can sometimes be cool but most of the time he's a poostain.
Hi my name is River J and I am on NextGenUpdate and I like men
