Undercover Lame

Someone familiar with writing javascript, htmls, code, and likes to spy electronically. These folks often feel that their sense of the world is better than others, justifying their need to spy. Often than not, they are lazy pukes, ignoring their own problems to examine others.

I swear there are some undercover lames in my life.

undercover yummie bird

A young man, usually from late teens to early adulthood, hiding his homosexual tendencies. An undercover yummie bird must be good looking, give away hints of homosexual behavior but yet deny any accusation of same sex physical attraction.

That man is looking at the guy all the time, I am certain he is an undercover yummie bird waiting to be discovered.

Undercover

If you talk to someone and their shoulder smells like a wife-abuser's nutsack... Don't say anything!

Undercover Guy "Hey, so... Give me the down-low on you whole job or whatever."

Overcover Guy *sniff* "Why do you smell like a nutsack?"
