Ziplining 

The act of unzipping a man's fly, snorting a line off of his erect penis, and then performing fellatio.

Dude ever since your sister got a hold of that coke, she's been calling me up for some Ziplining.

What's that?

She unzips my pants and snorts a line off my erection before sliding her mouth down my cock.

Zip-Lining 

The act of refusing to completely remove your pants before intercourse, and choosing instead to just pull your dick out through the fly. While unnecessary and ultimately will result in chafing, it is a very common practice.

Went on a date with Rebecca yesterday, things got hot and heavy fast, didn't even have time to get my pants off, so I was zip-lining her!

Zip lining in North Wales 

Zip lining in North Wales is a slang term for a gay facial gangbang and rimjob with a group of friends and strangers, where one participant is tied up, and the other participants take it in turns to slide into his mouth, until they ejaculate, and then they move onto the bum hole for finishing. .ie at the bottom of the Zip Lining.

Dave was looking forward to a weekend of Zip Lining in North Wales, but his jaw wasn't!
