OSM 

Oh Shit Moment
1. The point of realization that you forgot to do something important.
2. The point in time of a discovery that you forgot a step in assembly or development process when you realize you forgot an earlier step.
3. A moment of surprise occurring when some new information is discovered that provides a negative or detrimental result in an otherwise wonderful event.

Ricky had still another OSM when he discovered the hole in the condom he used last night.

hypertonic osmosis 

Sticking it in your homie or a guy the night before a workout. This allows testosterone to be transferred between the 2 dudes. This method was created by Shulk.

My workout went crazyy today because me and some guy I met at the gym last week did some hypertonic osmosis last night.

Osmanthus Wine 

Osmanthus Wine is, pretty self explanatorily, a type of wine made out of osmanthus, a plant that grows on the form of shrubs or small trees (mainly on Asia).

Commonly used as a joke between Genshin Impact players, as it is part of a voiceline repetitively said by the character Zhongli;

“Osmanthus wine tastes the same as I remember, but where are those who share the memory?”

Nobody knows what the memory is, now who are “those who share it”.

Person A: “I finally drank Osmanthus Wine after so long.”
Person B: “Does it taste the same as you remembered?”
Person A: “Yes, but where are those who share the memory?”
