Under-Onesie

Nat, when you bend over, I can see your Under-Onesie. I guess your torso never gets cold.

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.

Dave: :(

onsight

A term in rock climbing, describes completing a lead route without falling. The climber must not know anything beforehand about the route or have watched someone else climb it. See flash and redpoint.

I made the first ascent of this route by onsighting it because it was probably only a 5.7.
