A person who chews a whole pack of gum in one day. When they run out they suddenly get bad breath (withdrawals) and get another pack ASAP.
Dude John always has a piece of gum in his mouth. He's definitely a chain chewer!

Immediately after spitting out old, flavorless gum, the person pulls out a new piece of gum and starts chewing it.
Yeah, Ashley is unfortunatly a chain chewer. She's up to a pack of orbit a day now.
