A great Spanish word meaning "I give."
Although, it's not as great as "diphthong."
Doy quesosisimo vengaza!
Doy, you diphthong.
A vowel combination consisting of a weak vowel and a strong one.
It is more commonly used as an insult, seeing as it is a legitimately funny word.
There is a diphthong in "loud."
YOU'RE A DIPHTHONG.
