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!

Hanahaki Disease 

The Hanahaki Disease is an illness born from unrequited love, where the patient’s throat will fill up with flower, they will then proceed to throw, and cough up the petals, (sometimes even the flowers). One of the only ways for the disease to ‘disappear’ is if, the said person returns the feeling (it can’t be resolved with friendship, it has to be genuine feelings of love). The infection can also be removed through surgery, though the feelings disappear along with the petals. If they choose nether options, or the feeling is not returned in time, then the patient’s lungs will fill up with flowers, and will eventually suffocate.
There is no specific flower for the disease, but it’ll either be the crushes favourite type of flower, or their favourite colour. We can only hope for the patients, and pray that the crushes favourite flower isn’t a type of rose.

(The length of the disease varies with each person. But on an average, it will last up to 2 or 3 mouths, but sometime it’ll only last, a couple weeks).

~~~Example~~~
The sight was sickening, the body lay limp on the carpet. stained petals, and flowers surrounding them, swirling in a pool of their own blood. I took a deep breath. Then turned to the rest of the group, keeping my head low. 'Who said love couldn't kill?' I let out a low laugh.

"Darn you, Hanahaki Disease," I curse under my breath. Tears threatening to fall.

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.

Ed liked handshakes with snakes, at the park, on sunny afternoons.

Allen and his friends had a handshakes with snakes session, all afternoon.
