look up any word, like eiffel tower:
Eating a high-carbohydrate meal the evening before participating in a sports event in order to have lots of energy on the day.
All right lads, the big race is tomorrow, so I want carbo-loading at your dinner tables. That means lots of pasta, rice, and potatoes.

taking drugs and booze before a big event, Like Bernie Carbo admitted to before he hit his 3 run homer in the '75 Championship...
Man, I couldn't have given that speech if I hadn't smoked three joints, had 2 beers, a cup of coffee, some bennies and chewing tobacco before I went on...

Dude - that's some serious Carbo Loading!!!
