Word for someone who is annoying and pathetic, who also spends most time orbiting people [closed]
Such a person might be described as clingy.
Via Merriam-Webster:
tending to stay very close to someone (such as a parent) for emotional support, protection, etc.
I've personally always heard the word used with a negative connotation. Example usage:
Chances are you don't have much of interest in being the clingy one in a relationship. It comes with a whole slew of negative connotations — worst of all being jealousy.
