When you do somethingsocially unacceptable because you forget that there are people around. This is anything dumb that you would only do when you're alone, except you do it in public for everyone to point and laugh at you.
When you single-handedly are able to do incredible feats of humanity with very little thought or effort.
These could include but not limited to:
Awe Inspiring Parkour Vaulting over railing
Mind Boggling Quote Creation at 3am
Intense bouts of gaming for 8 hours straight
