Ondeadísimos is a highly expressive Mexican slang word derived from onda (wave or vibe), featuring the superlative suffix -ísimo which means "extremely" or "the absolute most."
In the song, Xavi sings "Los tiene ondeadísimos" to describe how this stunning girl has everyone completely crazy, infatuated, and mind-blown just by looking at her. It is a fantastic slang word to learn if you want to understand modern regional Mexican music and sound incredibly authentic!
In "OOTD", Mexican artist Xavi leans into social media pettiness after a breakup, and it makes for a super catchy track. The entire story kicks off right before bed: a girl posts on Instagram specifically "Pa' que lo vea ese tonto" ("So that fool can see it") to make her ex regret messing around. To send a loud message, she flexes luxury designer labels, dressing up in "Cartier y Celine también" ("Cartier and Celine too") for her "outfit of the day." It is a direct, modern revenge move: using a killer look on the feed to say "Mira lo que perdiste" ("Look at what you lost").
Xavi fills the chorus with sharp Mexican slang to describe her total command of the room. He sings that "La pleba está buena, pero a nadie pela" ("The girl is hot, but she ignores everyone"), where pleba is regional slang for a young woman and pelar means to pay attention to someone. With her red lips and designer gear, she leaves everyone completely rattled: "Los tiene ondeadísimos" ("She has them super tripped out / confused"). She also drives other envious girls crazy, shutting down any competition while letting her ex stew over what he gave up.
