swap-in 

An attempt during vaginal intercourse for one bro to secretly switch with another between thrusts. Thus the women has little to no idea that she is being railed by a different man.

"Catherine said you pounded her for over an hour last night! How did you do it?"

"Oh, my bro and I pulled a swap-in."

"Craig was doing this chick froggy style but starting passing out. Jon, unselfishly, swapped-in for him."

swap'd 

Short form for 'image swapped'. An image being hotlinked by an outside user is substituted with another image that bears advertising or is embarassing to the hotlinker.

I was linking to a picture of Tom Cruise on this guy's website, but I was swap'd when he switched it for a picture of Osama bin Laden.

Swap meet feet 

Swap meet feet is:
When someone has crusty feet with beat up toe nails, they are white, dirty and dry.
They need a serious pedicure and a fair bit of lotion to just possibly fix the problem. In bad case a doctor may have to step in with medication to heal the cracks and crust in and on the foot with salves and such. Mostly happens with sandels or other open toed shoes...
Anyone can get it but mostly trashy people do.

Oh man she is Sooo super hot, but did you see her feet? ...She had a hammer toe and swap meet feet from waaay back.

In fact I actually threw up just a little bit thinking about sucking on her toes... IS that weird?
