GIF - Graphics Interchange Format.

Hard G. for graphics. Not "jif."

The matter is settled.

Anyone who dissents gets sent to the camps.

I'm Dutch. We say "gif" with the hard Dutch "g" (yea I'm sure I'm speaking for all of us, shut up).

The point is that, unlike the English "dzj" (jif) or "gh" sounds, you can pronounce a Dutch hard "g" for as long as you want to. And therefore make it louder. And therefore we will win this argument:

ggggggggggggggggggggggggggggggif!

I throw peanut butter at people who get it wrong.
