A thing so big that the original "huge" is inadequate. Without the luxury of using body language or tone of voice to express the magnitude of something, and lacking a diverse vocabulary, the minions of internet forums require something more than "huge". HUDGE is that word. It's 25% longer and the spelling implies an extra half syllable in its pronunciation.
"You were killing it Bro! That jump was Hudge!"
"FKNA Brah, with conditions like this I'll be hucking Hudge air all day."
