Gremmin is someone typically under the age of 18, who often finds themselves in scenarios where a group of older individuals will find them annoying (hence them being Gremmin like). Gremmins can be seen in their gaming/goon caves playing Minecraft and trolling others.
"Danny has been whining to his big brother about me going into his house in Minecraft, he's such a Gremmin."
