TEER-fing-er
Here's a breakdown:
* TEER: Like the word "teer" (meaning to shed tears) but with a slightly shorter, more clipped vowel sound.
* fing: Like the word "fing" (the first syllable of "finger") with a slightly stronger emphasis on the "f" sound.
* er: A short, neutral "er" sound similar to the "er" in "her" or "stir".
So, the emphasis is on the first syllable ("TEER"), with the other syllables being pronounced more quickly.
