Drunken Karaoke
When a female is going down on a male, and she so drunk she can't seem to put the penis into her mouth, yet she's moaning at it as it sloshes around her face. This is usually accompanied with a fair amount of saliva which in turn, smears her hair onto her face and looks like sweat from a live concert performance.
My god. Last night was insane! She totally did a drunken karaoke.
