A sesh gremlin is a mysterious creature from the sesh . They usually are found in forests, at the 24 hour garage looking for cheap beer , at about 6:30am on a Monday.

The sesh gremlin is a true master of the sesh and knows every trick to always make a Rollie out of thin air when everybody is passing out from train wrecks of comedowns. A sesh gremlin is a hardcore sesh head that rarely sleeps, and is a saviour in the rave community.

"Bris-Tek was fucking insane! So many cool heads and sesh gremlin 'sman hahahahaha..."

Seshbox 

A cool and fun gaff where the session never ends. There are so many sessions that each one blends into the next and the gaff is a never-ending box of sessions. There's drink, there's lines, it's 4:20 all the time.
The whole room serves as a large room shaped ashtray. That smell is never coming out. Your shoes are likely to get stuck to the floor, you may leave without them.

Oh hey do you want to come to Aisling's gaff tonight for a few drinks? I'm in I hear it's an absolute seshbox!

Youtube Session

When a group of friends sit around a computer and share youtube videos that they have found in the recent weeks, and take turns sharing said videos.

In a Youtube Session, there is an unspoken rule about taking turns, usually in a round robin style, but is often broken when someone exclaims that everyone "has to see" the video they have in mind.

An abbreviation of "Youtube Session" would be "Youtube Sess", with "Sess" pronounced as "Sesh".

"Charlie, great Youtube Session the other night. I didn't know about Wombo Combo until Heather showed me."

"Oh, my, god. You NEED TO SEE THIS VIDEO, TIME FOR A YOUTUBE SESSION"
