"I raise 20"

[Meatmaw]

I've been getting confused and hearing differing opinions. When I hear the phrase "I raise 100" or "Raise 100", I infer it to mean "I call and raise 100". Is there some segment or some publications, shows, whatever, where the phrase "I raise 100" means "I raise the bet up to 100"? It's been confusing me when people say "raise 3BB" and they mean "call and raise the bet to 3BB" etc.

Which is it, or is it just all over the place?
