A lovable harmless goof, you can control, and who is at the mercy of your whims, who is available to you sexually, emotionally and financially, at any moment of the day.
I was feeling so lonely after my boyfriend dumped me, I felt unttractive, unwanted and broke. So I called my friend Steve, who is a totally "Jeffy", to take me out, listen to my problems and pay for me. Although he gets very aggressive at the end of the night and I feel, given the opporuntity he would rape me, I still feel safe around him.

The single greatest human being alive. Always on Omegle or ChatRoulette, a sweetie all around, but kinda goofy and obsessed with sex. Has troubles answering his phone, or Skype. Very easy to love, very very hot, and someone you never wanna let go of. Don't ever lose your Jeffy or you'll lose your heart. <3
My god, did you talk to Jeffy last night on Skype?

Yeah, but he didn't answer until the third time.

Jeffy is a term used, mostly in Ontario, to describe one who's actions have left no doubt in everyone, that he is a moron and/or just a Tard.

Do not mistake with the Name of an individual.
