Jamkinator 

To be self inflated to the point you are delusional. Typically found in grown ass old men that have noodles for arms. The most unoriginal self given nickname, not to be confused with Terronator. Dating back to the Oregon Trail.

Ride your Jamkinator ass back to Oklahoma !

janinator 

Noun, originating somewhere in the Pacific Northwest. A girl who is superlatively awesome, exerting her superiority wherever she goes (but in a non-pretentious manner; more of a transcendent, aloof hipness). Possible association with "terminator," though in an innocuous (not lethal) sense.

Alternately: An enigmatic and delightful person.

Partygoers felt keenly aware of their superficiality when a janinator walked into the room.
