The feeling a male expeirences when he has ejaculated inside his pants and continues to wear them. As the semen makes the pants feel wet and squidgy, like the pants are made of some strange spongy material. Opinions of the feeling vary, some think that it is nice while others detest it. It usually ends in the pants being changed or washed within 2 hours of the incident.
"Shit mayne, I just blew a load in my pants and now i got mushy pants".
