Sleepstreaming 

The point you find yourself, between the tiredness that grows heavy on your eyes, and being in full fledged sleep. You may be in fits and starts of fading into sleep for a few seconds, before you wake out of it; the constant gliding back to sleep would be considered sleepstreaming.

David grew weary on his seat in the glow of the TV, he'd been sleepstreaming and kept waking up a few seconds after falling limp in the couch, obviously beaten by the day's labour.

crowd slipstreaming 

Walking directly behind someone who is pushing through a crowd, to avoid having to push through the crowd yourself. Only works if you stay in the empty area directly behind the person in front of you. Usually done behind someone tall or buff.

Guy 1: "Dude, how did you get to class so fast?"
Guy 2: "I did some crowd slipstreaming behind that tall guy over there, it saved me a lot of time."

Mobile Slipstreaming 

Walking directly behind someone so they can navigate and you can stay glued to the screen.

Dude 1 - Hey, are you taking a photo of the chic's legs in front of you?
Dude 2 - Nope, mobile slipstreaming buddy
Dude 1 - Dubious bro, very dubious
