The act of indulging in masturbating with feces using only the right hand, while at the same time with the head is inserted into a toilet (Used or unused I personally prefer used) the left hand is then spat on for lube and used to finger the anus furiously until ejaculation.
Bro last night my girl sent me nudes so I sent her a video of me romp slompin. I guess she didn't think it was as hot as I thought it was because now i'm a registered sex offender.
