look up any word, like bukkake:
(noun) an internet troll, usually male, who has lost all touch with reality. Common behavior for a Yukonjimmy is spouting nonsense speeches or rants circling their own self importance and wit, though they usually have a serious lack of both. A person with a severe persecution complex which helps to stoke the flames of their own delusions, burning all personal bridges until they stand alone within the ashes of their lives to continue blame-ranting against anyone and anything besides themselves.
After witnessing his loss of self control for the millionth time, the sister of the yukonjimmy had to place a restraining order on him to prevent him from lighting his body on fire again to welcome the aliens to earth during the family Christmas party.
