ETH 

Used by UFO enthusiasts as an abbreviation for "Extraterrestrial Hypothesis," referring to the belief of some that UFO reports represent sightings of alien spacecraft.

I neither accept nor reject the ETH. Quite frankly, I don't know what UFOs are - they're UNIDENTIFIED.

ETH 

Email Transmitted Homosexuality (ETH) is the term to describe emails recieved from male companions that depict any of the following: 1. Kittens 2. Sunsets 3. Beaches (not containing naked/scantidly clad females) 4. Puppies (exceptions being Dobermans, Rottweilers etc) 5. Couples (not in the act of sexual depravity) 6. Or other topics which cause the recipient to question the sexuality of the sender.

ETH is the electronic version of AIDS. ETH can be voided only by subsequent emails from the sender that contain (or make reference to) vaginas. Either context must adress the touching and/or penetration of said vagina.

Dude 1: "Buck sent me another ETH..."

Dude 1: "A slideshow of kittens. What a fucking fag!"

Crazy aaaaaaasss. Eth is a gal who is so fun to be around. A night out with ole eth is always a win. She knows how to have a good time. She loves music and dancing. And WILL rap for you. But she does get paranoid easily so be careful.
