when you curl up into a ball and your penis lands in your own mouth, so you think its funny and go to school telling everyone that you blew yourself.
"Hey guys i just sucked my own penis," says guy number 1.
"Ew. You mean you went devonpalmering? Thats disgusting, dude," responds guy number 2.
"I did and I am proud of it," remarks guy number 1.
Guy number 2 is so grossed out after hearing that, he walks away and never speaks to guy number 1 again.
