Jerseytard 

A stupid sports fan that wears a completely unrelated jersey to attend a game. Yankees and LSU fans are notorious jerseytard.

Chris went to the Dodgers-Padres game with us and he wore his Notre Dame football jersey---total Jerseytard.

jerrytard 

When an elderly person loses all mental faculties and slips into the retard zone.

The term originated when a mass number of baby boomers who were not previously retarded, entered into their geriatric stages and displayed aspects of mental faculty loss. "Retardation" This resulted in the need for expansion of English medical jargon.

User 1: did you see gramps last night at the party?

User 2: ut was only a matter of time before his jerrytardation sunk in.
