A "Hession", or somebody who arrives at a social event dressed too formally for the occasion. At length this person can become very aware of this extravagance and indulgence and consequently become very insecure.
Check out the "Hession", he is wearing a freaking tux to a barbecue!! How overdressed can you get!!!?!?!
To arrive at a party more fucked up than anyone already there
We smoked a bowl in the car, and when we got there we realized no one at the party was high except us, and had no idea we were overdressed.
