Middle-aged Onset Dementia 

When you are old enough to remember events that happened 10-15 years ago but can't quite remember the exact details of the story. This is usually solved by asking others who were present to fill in the details. This type of dementia can be caused by several factors including drinking, having too many experiences, or by simply not choosing to remember your horrible past.

I can't believe I was actually at a Spin-Doctors concert. Many thanks to my Middle-aged Onset Dementia for helping me not remember that part of my life.

Delayed Onset Snowness 

Like delayed onset soreness, the lower back and other pain in the days after moving copious amounts of snow off of sidewalks, cars, etc.

After hours of shoveling yesterday, delayed onset snowness is making my lower back squeal like a pig.

Sudden Onset Confidence Syndrome 

When someone, through some means (usually weight loss), gains a large and sudden boost to their confidence that turns them into egotistical dickheads. It can also exacerbate egos for people who were faking it and now that they have real confidence it makes them appear like they're bragging all the time.

Fella: Hey, did you see that Gary lost a ton of weight recently?
Mate: Yeah! Notice how he hates fat people now? And he scoffs at chicks that he previously would have crawled dick first through a valley of glass just for them to notice him?
Fella: I have!

Mate: Ya boy's got a bad case of Sudden Onset Confidence Syndrome.
