shooting glitter up her ass

When significant praise is given to a person who is undeserving of such praise; when everyone thinks this one person is so amazing, when in reality they're basic, unimpressive, and overrated

"everyone's always shooting glitter up her ass for being such a great actress, but she's painfully mediocre; borderline bad."
"Janet always shoots glitter up her daughter's ass for being a singing prodigy, but in reality, her daughter is unimpressive."
