gigachad
What does gigachad mean?
An exaggeratedly capable, confident and admirable person — usually used half-jokingly to praise someone for a strong or unbothered move.
"He fixed the bug and refactored the whole file. Absolute gigachad."
Origin
From a meme built around a stylised black-and-white portrait; "chad" long meant a confident alpha figure.
