Antifreeze is that greenish yellow liquid your dad puts in the car. It's ethylene glycol. It keeps the car's cooling engine from freezing. It's done in cold places and it's a tradition that goes from generation to generation. Don't drink it though, or you'll die. It's sweet tasting, but deadly toxic if you drink it.
You: Dad? What's that yucky green stuff you're putting in the car?
Dad: That's antifreeze! Someday you'll follow in my footsteps and winter-proof your car engine.

Any type of amphetamine. Usually popped to get pumped up for something serious or something you would otherwise be afraid to do. Mostly adderall but sometimes vyvanse also. Called anti-freeze because it keeps you from freezing up in situations that could mean life or death.

When you see your bro drinking a Smirnoff Ice, look him in the eye, say "PUT THAT DOWN!", and punch him in the face.

The opposite of icing.
Bro...if I EVER catch you with a Smirnoff Ice, I'm gonna set you straight and anti-freeze you.

An alcoholic drink that one may make by mixing Golden Grain and green Hawaiian Punch.

Also known as Hunch Punch if Golden Grain is mixed with red Hawaiian Punch.
Let's mix up some antifreeze in a gas jug so if a cop pulls us over, they won't suspect shit.
