One usually "touches cloth" when he/she passes gas and pokes out a turtle head while their pants are still on them. Then a peice of poo then touches their underwear leaving a small stain. This is usually uncomfortable to walk around with.

1) to have a turtle head pop from one's rectum before underpants are removed

2) to break wind with more force than expected, and to cause fecal matter to come in to contact with one's underpants before being able to suck it back in

to be near the point of defecating in one's pants after waiting too long
