swishass 

That not so fresh feeling between the cheeks of your ass.

Like when sweat mixes with leftover chunks of shit, and lubricates your ass cheeks.

After Tom ate the bag of Pringles with olestra he had swishass for a week.

swishashima 

Another way of describing a swish in basketball. Opposite of brickasaki.

I was drillin those swishashima's in Vasu's eye all day long.

Swish Ass 

Someone who wipes their ass, but notcompletely. When your ass starts to sweat, you leak the leftovers from your earlier dump

Man it's fucking hot outside, i got the worst case of swish ass ever
