A chemical that can be inhaled, makes you retarded (The intoxicated retarded, not mentally). Usually put into balloons and inhaled. Has a sort of sweet taste. Only lasts around 30 seconds, sometimes you will feel a little something for a couple minutes. Also can give you the "wah wahs"
"Why is he staring at the wall laughing his ass off?"
"He just inhaled a whole balloon of freon..."
Freon is a trade name for a chemical envented by Dupont 70+ years ago to replace dangerous, poisonous or explosive gasses used for refrigeration. The chemical is the famous CFC. Comonly called R-12, however, there are many other refrigerants (like R-11, R-502). These chemicals were pulled out of production in 1995 due to environmental concerns. The actual environmental impact of CFCs has yet to be determined.
