Irish Slip 

When you leave a group event without the other party knowing you have left.

Alex was out with Tommy and the gang. Tommy and the gang were having a great time with Alex. He went to order a drink and when he returned Alex had vanished. He had done the Irish slip.

When you leave a bed after copulation without the other party knowing that you've left

Mike slept with Alexandra. When the parking lot lights were too bright and the fan was too loud to sleep, Mike used his feet to check her ID to get her name(in case she heard him leaving), and to gather his clothes, before he pulled an Irish slip, and headed back to his own bed.

Irish Slip n' Slide 

When you open someone's legs and spit on their balls.

There was this guy at the bar last night and he thought I was gonna give him oral. I gave him an Irish Slip n' Slide instead and got outta there.

Slippery Irish Skip-Devil 

An impish, creepy little man who enjoys irritating a person to no end by skipping circles around a person, (usually while they're walking) all the while singing bad irish pub-songs, & sea shanties, & being impossible to catch by the person he's annoying.

Bill: Ok ok, HA HA. Cut it out, you're annoying me, & you almost tripped me.

Slippery Irish Skip-Devil (skipping): "Now Fiddler’s Green is a place I heard tell, where the fishermen go if they don’t go to hell"

Bill: Enough! Shut up, you crazy little bastard!!

Slippery Irish Skip-Devil (skipping): "Where skies are all clear and the dolphins do play, and the cold coast of Greenland is far, far away!"

Bill: AAAAAAAAAAARRRRRRRRRGGGGGGGGHHHHH!!!!
