When an experience is marked with hilarious laughter and you just shake your head from the pure redonkulous of the situation you just say hildonkulous. Its a combo word.
Its quicker and smoother to say than hilaredonkulous which means the same thing. Either way the situation is just hilarious and redonkulous and ridiculous and a hot mess and if you want to go one step further a hot tranny mess.
"That story is hilarious with how much of a hot mess it all is....its just hildonkulous!
