GARG

Garg is the last name (Leonard Garg) of the guy who runs away in Hotel Transylvania when he is with his friends while they are editing his face on an app. He is probably running away to go pick up some chicks because he is horny. Garg has now evolved into a saying, rather than just his last name. When you're a "garg", it means your weird, funny, or maybe you're just calling someone a garg because you want to. Sometimes "garg" is said when you get a burst of energy, but it typically comes out as more of a "GUUUGGGG" than a "GARG!". Usually when that happens, make sure you go up to someones face nearby to share your "GARG" outburst with. This may weird them out, but once you do it enough, they will start to catch on and do it too!

They were so excited, so they both screamed in each others faces: "GARG!!!!"

They were scared, so they hollered: "GUUUGGG"
