when a ninja comes into your house at 2:45 am while your sleeping and sticks his penis into your left ear and cums out your right ear and that he eats all you your grandma's soup.
"Man! I think I had a ninjagasm last night! I woke up with some sticky stuff coming out of my right ear and all of my grandma's soup was gone!
