Gablos
A Gablos is a person who thinks they're smart but actually have no idea what's going on. You mostly hear it in Utah, where people still talk like they're in a weird commercial from the 1990s.
'He’s a Gablos. He still thinks the phone is a toy.'
'She’s a Gablos. She tried to text me with her fingers like it was a game show.'
'They’re both Gablos. They still think the sky is a ceiling.'
