ShitAss means someone has shit on their ass because they do not wipe. Usually they do not smell very well and you can see brown spots from all the shit around their ass. It is not a very nice quality to have. Usually males by the name of Noah have this ShitAss quality and donât like wiping after they drop a dump.
âEw whatâs that smellâ
âThat Noah dude over there has ShitAss and it smells badâ
