Pompous
Exaggerated, Excessively Grand
い adjective
Someone tries to make you look up to them... twice. That's too many times to look up to someone. When this happens, this person must be pompous.
仰々しい is a relatively formal word often used to describe something that feels exaggerated or excessively grand. It can refer to a speech, ceremony, or behavior that comes across as overly formal, showy, or dramatic.
The reading is the same as the one you learned with the kanji, x2 with a しい added on for good measure.
仰々しい言葉遣いをする人は嫌いです。
I hate people who use pompous wording.
