Amateurish
Amateurish. Adjective. Characteristic of an amateur, esp. in having the faults or deficiencies of an amateur; inept.
I don't think "amateurish" quite does justice to the level of Lisa Rinna's incompetence -- maybe the TVGuide Channel, when hiring celebrity correspondents, ought to prioritize the ability to speak coherently over quantity of lip collagen. The interview above, with Casey Affleck, is cringe worthy. Shameful. Embarrassing.
Ick. But all reference to her terrible interviewing style aside, the gum was disgusting.
Hey, remember the good ol' days on Three Mile Island when we used to take 'Tang Baths'?
Except, it wasn't Tang at all.
