Mentááál comes from the Czech word mentál, used here as a slang-style reaction rather than a formal statement. The elongated spelling in the title mirrors how the vowel is stretched in the audio, which helped it circulate as a short soundboard clip. Its spread is typical of reaction sounds: one expressive word, no context needed, and a delivery that can be dropped onto almost any chaotic clip. It remains popular because it instantly turns confusion, bad decisions and absurd reveals into a shared joke.
