The show follows Johnny Bravo, a dim-witted muscle-bound blonde voiced by Jeff Bennett, who wears a pompadour and is styled after Elvis Presley and Fonzie from Happy Days4. He lives in Aron City with his mother, Bunny Bravo, who still treats him like a small child, and most episodes revolve around Johnny trying to pick up a woman and getting rejected, usually while taking a comedic beating for his trouble4. Recurring characters include the little neighbor girl Suzy, the nerdy sidekick Carl Chryniszzswics, and Pops the diner owner2.

The humor leans on exaggerated masculine posturing, endless flexing, cheesy one-liners, and Johnny's signature reaction to any attractive woman: a slack-jawed "Whoa Mama"7. Visually the show mashes up 1950s Americana with the loud, boxy Cartoon Network house style of the late 90s, which is a big part of why clips and GIFs still get shared as reaction material online3.

Fans typically use Johnny Bravo as a stand-in for over-the-top masculine try-hards, dropping GIFs of him flexing, combing his pompadour, or shouting "Whoa Mama" whenever a thirsty comment or reaction is called for8. Reaction clips from his rejections are common on Tumblr threads about failed pickup attempts3.
