StalkerTalking is when someone, who you usually don't really know, strikes up an unwanted, meaningless, uncomfortable conversation with you everytime they see you.
Karen was just sitting there, minding her own business, when that creepy guy started stalker talking to her again.
The act of mumbling and slurring words simultaneously while speaking, resulting in a non-understandable statement.
Jamie: Hey, how's it going?
Hannah: Pretty good, actually; I just got a dubahbgdaboh...
Jamie: I'm sorry, what? You were gravy talking big time just then.
