Caspering 

The art of ghosting someone in a friendly way. When you don't have the heart to full on ghost them, so you start cutting and reducing all interactions until they take the hint and give up.

Take forever to reply and only give short responses that can't lead to further conversation.

Similar to gas-lighting but without the intention of possible future interaction. Letting someone down gently.

Friend: how did it go with that girl

You: she's nice but I don't want to see her again so I'm caspering her til she takes the hint

Jaegering 

Noun: Jaeger (pron. jayger)
Verb: Jaegering (pron. jaygering)

Usually when intoxicated, but not limited to, the act of Jaegering is to randomly lay down on the floor.

This can either be face down or flat on your back with limbs generally extended outwards.

It is not known why a person choose to Jaegar; most likely for a bit of cheeky relaxation during an alcohol fuelled evening.

Jaegaring can often result in being escorted from the establishment of the floor you've chosen to lay upon.

Girl: Hey, have you seen that girl on the dance floor?
Guy: Yeah, she's doing a spot of Jaegering.
Girl: I know, I see her here a lot. She loves to Jaeger!
Guy: Uh oh, the bouncer's are throwing her out.
