We made up the word wab in Scotland, I can guarantee it. The real definition goes something like this:
Wab (1): n A person who acheives intellectual victory over another, usually by a technicallity, often with a large degree of smugness.
Wab (2): vb To acheive intellectual victory over someone, usually by a technicality or illogical argument, often with a large degree of smugness
The wabacha, or vagina dentata,is a big scraggly vaj with teeth in it. Kinda like if your grandma stuffed her dentures in her snatch. Yuk.
Mythology: A chrome purple poon-monster with an insatiable cockhunger and gnashing teeth like the predator, but its your girl.
