I pronounce it "giff" because (as already mentioned) it stands for Graphics Interchange Format. I'd never heard it differently until my habits had already been permanently set.

To really annoy people, you can pronounce it "gifffffffff" and really drag that f out.

Or, start calling another file fomat "j-pej".

Hold on I need to get my peanut butter changed at Giffy Lube...
