Жирный чек [zhirnyy chek] literally means “a fat check,” but жирный [zhirnyy] is slang for something substantial, impressive, or loaded with money. In the song, самый жирный чек [samyy zhirnyy chek] means “the biggest” or “most generous check,” highlighting the flashy spending and money-focused mood.
This one is a flex anthem with the roles flipped. The hook goes "И мы катим, катим, катим / На кади, кади, кади" (And we roll, roll, roll / in the Caddy, Caddy, Caddy). "Кади" is just a slangy short form of Cadillac, so picture a slow cruise in a big shiny car.
The twist is who pays. "Твоя женщина сегодня за тебя / Здесь все оплатит" (Your woman will pay for everything here tonight, for you). She writes "Самый жирный чек" (the fattest check), throws him "пару сотен" (a couple hundred) so he won't miss her, and tells him "не нужны бумаги" (we don't need papers). "Бумаги" here can mean paperwork like a marriage certificate, or money; either way she's saying she doesn't need anything official to be with him. Honestly, it's a pretty funny reversal of the usual rap money talk.
It isn't all about cash. There are soft moments too: "Я в твоих объятиях" (I'm in your arms) and "Наверно это любовь" (Maybe this is love). Then the money comes right back with "Бэнкролл крутится" (the bankroll keeps spinning), a borrowed English word, plus English lines like "Money on my mind, please don't waste my time." Good words to grab here: платить / оплатить (to pay) and счёт (the bill), which turns up again and again.
