The act of secretly yet abundantly refilling someone's cup, wine glass, or mug with alcohol.

At Thanksgiving last year, my cousin uncle Jeff’d me last night and now, I have the worst hangover ever.

Uncle Jeffery 

When you wear your uncles pants and slip a slim Jim into a desired hole and swirl it around and then make your partner eat while calling you uncle.

I asked my partner to get me a slim Jim because I needed a snack and he offered me an Uncle Jeffery.
