Nah, that's not a real thing. Otherwise AIDS would be pronounced UHIDS because Acquired is pronounced UHquired. And LASER would be pronounced LAHSEER because the A would be like in Amplification and the E like in Emission.
& the guy who created the GIF says it's pronounced JIF. He's like the parent of the word, so he gets to decide how its name is pronounced.
So say it like JIF or I'll shoot you with a LAHSEER gun!
