The state or likeness of being beyond godly-- more than 'epic' or 'uber'. Being siddy denotes the possibility of any lower status than itself and can be considered the pinnacle of spiritual enlightenment or physical achievement in life; it can be compared to reaching Nirvana, one really good high, or sexual gratification.
"Did you see that movie, 300? Man, that was siddy!"
A guy who is down to earth, sweet, smart and really tall. He can be serious and blunt from moment to moment. Most of the time he is funny and nicely-honest. Siddy's tend to be more feminine then masculine, making them ideal for a girl who is looking for someone who understands them clearly. Siddy's are one of the best types of guys to be around.
a bum. a poor bum who lives on the streets who always wears unwashed pink spotty socks and carries a whip. Always treat a siddy with respect or she'll fart on you. Whos head sounds hollow when she whacks it after having eaten parsnips.
