Depends on what you see as a gigachad. Fuckboy type? Then he isn't. The type as in "an exemplary male figure", then yeah, seems so.

The first one was the OG usage, and second one evolved over time from memes. To sum up that version: the really cool and respectable type of guy (chad) is actually the one who respects his women, supports his fellow guy friends, does something amazing, and generally is a good influence rather than a toxic one
