1. A gay baby

2. A child of gay parents

3. A person who looks like a mixture of two people of the same gender. Basically, it's like a look-a-like, except that you can't decide whether it looks more like one person or another. But if those two had a baby, despite they're both being a man, it would look like that.
Person1: Dude, I just found Alan Rickman and William Shatner's gayby, by the bar over there.

Person2: Oh, I totally see it.

Contrary to popular belief this is not a baby of a gay couple. It is the disease resulting from being bitten by a homosexual dog (often a Chihuahua). The infected are overwhelmed with a desire to suck cock, irrational fear of water, and a taste for Beggin' Strips.
"Dave was a lot cooler before the Gaybies"

Women are impervious to Gaybies due to their inherent desires to suck cock and irrational fears
