When at a party, while everybody is drinking, you are sipping on non-alcoholic beer.
The word and usage comes from the red cans of Old Milwaukee Non-Alcoholic beer.
Normally, red canning it, refers to Mormons who don't drink alcohol (5%),
responsible people who don't drink alcohol(5%), or
potential sex offenders who generally do drink alcohol but just are looking to "score" on a pissed-drunk young (most likely under-aged) woman (90%).
Despite the reason, every person red canning it, appears to be drinking and therefore:
1. receives no questions about not drinking;
2. does not appear gay;
3. receives minimal
peer pressure;
4. gets all the numbers; and
5. makes out with all the girls who are drunk.
