Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means drunk so the verb vocab version is to be drunk.
This drunk feeling also happens to some people in boats and cars. But we call that to be seasick or to be carsick. You aren't actually drunk, but you feel like you are (and you're probably gonna puke, yuck!).
I'm not drunk, yo (よ). YO. I'm not drunk, yo. YO. Yo, I'm not drunk. Yo.
Everybody got seasick and puked all over the ship.
