Gabriel DropOut began as a manga by Ukami in 2013 before its 2017 anime adaptation, where Satania McDowell became a fan favourite for her delusional demon act. Voiced in Japanese by Naomi Ohzora, Satania delivers her bwaaa as a proud, villain-style laugh despite usually being teased, tricked or defeated seconds later. Clips of the sound spread through anime edits and soundboards alongside other short character calls like Tuturu and anime ahh, and it remains a go-to shorthand for smug overconfidence that is about to collapse.
