shoulder sniffing 

If their is a group of friends and somebody (not a friend) tries to join in the conversation but just finds themselves lingering on the outskirts, getting nothing but people's backs to them, they are shoulder sniffing.

Who the hell is that guy shoulder sniffing? I swear I've never spoken to him before.

Shoulder Trout 

When a co-worker hovers over with you, with their crotch resting on your shoulder.

Dude I was looking at a wiki and the dude 2 cubes down from me shoulder trouted me. I had to wash my shirt.

shoulda coulda oiled

An expression used in situations where one could have avoided a poor, destructive, or unpleasant decision by smoking hash oil instead. Kind of like the V8 commercials, except replace V8 with oil.

Guy 1: I got drunk and totaled my car last night. I feel like such an idiot.
Guy 2: Shoulda coulda oiled.

Guy 1: Man, yesterday sucked. I had to meet Jenny's parents and they totally hated me.
Guy 2: Shoulda coulda oiled.

Guy 1: I can't believe Bob overdosed on heroin. He had his whole life ahead of him.
Guy 2: Shoulda coulda oiled.

Shoulder-Dicking 

When you're seated next to someone who has a standing desk, creating the awkward situation of having their dick at your shoulder height.

Brad is great, but honestly ever since he got a standing-desk I feel like he's shoulder-dicking me all the time. Every time I turn around his dick is right there on my shoulder.
