Ade

Alison and I often use this word in conversations that also feature "barform:"

ade, noun. Any beverage designed principally to rehydrate one and replenish one's electrolytes, such as Gatorade or POWERade.

Example: After a 3-hour ride in 90-degree weather, I could really go for some ade and barform.

By the way, as Alison can tell you, my favorite flavor of ade is 32 ounces.
