Maternal Hand Save 

When mothers or mother-like figures put their arm in front of your body as if to guard you from an impending threat.

May occur if:

a) Your mom is driving and must suddenly stop short, break hard, or perform any other semi-dangerous driving maneuver especially in response to someone else's bad driving
b) If you are about to cross a busy intersection and she wants to protect you from oncoming traffic and/or keep you from crossing before she gives consent

Mom enacted a Maternal Hand Save when a car suddenly turned in front of ours.

bavarian handshake 

The act of passing one's hand through one's own lederhosen crotch flap, to shake someone else's hand. Popular at German (and German-themed) festivals.

Franz's Bavarian handshake caught me off guard--but what a grip!

Vagina Handshake 

How Trump Greets a beautiful woman.

When you're rich or a celebrity, you can do pretty much anything you want, so when I meet a beautiful woman I walk right up to her and grab her by the pussy, and give her a vagina handshake.

Nervous Flyer Handshake 

When the person on the flight is apprehensive to fly so you help them relax. Typically by manual sexual stimulation.

Woman in the seat next to me was worried about flying. Let her give me a nervous flyer handshake to calm her down. Not sure about her but I need a smoke.
