Ave Rat 

The street kids of the U-district were looked down apon. Kicked out or rejected by their families some as young as 10-12 for being homosexual, transgender, the wrong religion, artists, musicians, etc., ran away because of abuse or neglect and barely escaped, or were abandoned. They all ended up on the streets through no fault of their own. Shelters and organizations turned a blind eye because they didn't meet the "criteria" (blame the Becca bill) and other organizations require an address. In the early 90's they sought each other out, banded together for safety and survival and began to clean up their street home. They did what the police couldn't do, lured out the pedophiles and drug dealers, for the police to take away and drove out the scum, not just for themselves, also, for the other inhabitants. Pooling together with housed friends they set up communal homes to be used by all for safety, warmth, food and to care for the sick and injured. They formed a community with their own rules and used society's cast offs and abandoned resources for survival. They did not rebel to be different, society had turned its back on them. As the Ave Rats have grown and become productive members of society, cops, lawyers, techs, engineers, etc., they stil come together to catch up on each other's lives, help each other, and help the new street kids, (dubbed "Ave Mice" by many of the original Ave Rats) who are struggling to survive every day, and the Ave Rats are trying to help.

I am proud to be an Ave Rat!

river rat 

In poker, the river is the fifth commmunity card to come up and the river rat is a person who called all wagers, with no apparent hand and a minute chance of winning, in order to catch some miracle card and 'river' any legitamate betting/raising hands.

I flopped a set, pounded it the whole way, and that river rat Mario called all the way just to hit a gut-shot.
