Similar to Motor Boating, but accomplished by placing your face in the other persons' ass cheeks instead of their breasts.

When your underpants are moist and smell like the morning on a lake when the pontoon boat is covered in mist.

A pontoon donga is any house built on swamp or flood plains with a waffle slab consisting of lightweight polystyrene pods (waffle pods) in a grid pattern on the ground before being framed in rebar and covered in concrete. These foundations are often poorly laid and will crack during or shortly after settlement.
Those imports studying a Diploma of Uber bought that pontoon donga right before the rains hit. I hope they got insurance, as it's starting to crack right up the middle.

"He just handed me a duffel bag of cash and fled the state, I was completely pontooned"

I went to motorboat that bae but turned out she was wearing a padded bra, so when I got down in there, it was more like pontooning.
