Someone who always backs a Kickstarter the moment it goes up, and always at the highest tier.
"Hey bro, you see that new Praxis Kickstarter?" ... "Yeah, man, I pounced on that shit instantly. Top Tier!" ... "You're such a fucking Jeffie!"

"That new RPG Kickstarter last night ... I Jeffied that shit quick!"
