Onsen 

An onsen is a Japanese style public bath using volcanically heated hot water from the ground.

The term onsen is often used in the Japanese language in reference to the bathing facilities surrounding hot springs.

Onsen, when translated into English means 'hot spring', which can lead to confusion and miscommunication.

After watching the monkeys in the hot spring, do you want to go to an onsen?

Sudden Onset Autism 

Sudden Onset Autism, or S.O.A for short, is an extremely rare condition of unknown origin. Development of this disease is both abrupt and severe. As of now, the pathogenesis and mode of infection have eluded even the most qualified of research teams at Harvard, Hopkins, and Yale. Some have suspected that transmission occurs through contact with an infected person, especially prandially. There is still hope for a cure, although we may be decades away.

Infected Person: Hey man, let's go grab some lunch
Healthy Individual: what?! It's 3 in the morning. What's wrong with you
Infected Person: Well... it's lunchtime somewhere!
Healthy Individual: Oh God, you have Sudden Onset Autism... Please go away from me!

Early onset necrophilia 

When the elderly have sex, pushing apart a grilled cheese sandwich with a loose sausage you found in the back of the freezer.

I walked into great aunt Bessie's room and her and uncle Boris were going at it, 19 to the dozen. The doctor said it's 'early onset necrophilia' and prescribed me some eye bleach.

Early Onset Caucasia 

Mental Illness found in white women aka“Karen“ worsens with age.

Symptoms include/not limited to Attacking others then playing victim when authority arrives. Knowing you're deadass wrong, STILL want a manager. Calls 911 on anyone doing anything, while black. Use police as threat to harm, not service to help, denys police brutality. Theft of music, machinery, property, wealth, ideas... literally ALL OF THE THINGS IN ALL OF THE PLACES.

Know causes include /not limited to, insatiable thirst for chocolate, Only have a tiny vanilla, raisins in potato salad, thinking Jesus was white, short strokes, lack of exercise or results, specifically doing squats.

Cures- Hennessey, Atlanta, swap paprika for Lawrys, vitD super veggies resembles eggplant in size &girth. That D taken orally, anally, vaginally & swallow juice or use as facial (can’t take too good of care of that skin!) Start by using only 1D at a time but the only snitch here, is you!

NOTE: Seeking medical advice is NOT recommended as it will trigger EOC fits due to the Doctors sudden disregard for your well-being.

FUN FACT- EOC is unique because those without it, suffer from it the most.

- Becky Snow

Knowing she was at risk of contracting EARLY ONSET CAUCASIA, Amber got divorced, moved to Atlanta, vaguely remembers drinking Hennessey, is making a conscious effort to regularly consume her veggies and is no longer at risk of contracting this horrific illness.

on se casse 

It means in French, let's leave. Se casser in French really means to break. But in slang, se casser means to leave. On is a familiar way of saying, We. Thus: Let us (we) leave. The se is a grammatical word and this is not a French lesson so let us leave it at that.

Cette boum est morte, on se casse!
This party is dead, let's leave!
This party is dead, let's get the hell out of here.

Voilà la police, on se casse!
There is the police, let's get the hell out of here!
