Well, you see, the g in gif stands for “graphics” which is ultimately from Greek “γραφικός,” and because this is the 21st century, γ in front of a close front vowel is pronounced as neither /g/ nor /d͡ʒ/ but rather /ʝ/, which is pronounced a bit like English’s y, so in its purest rendition gif is really pronounced “yiff”, which doubles as homage to the online communities that OP frequents.
