Jumbo Schleechum is a slang term used to describe the physical and habitualcharacteristics of a large, nasty, smelly, hairy, whorish, mammoth of a woman. A Jumbo schleechum is not as bad as a Yetti but far worse than your average band nerd.
I got drunk at this redneck bar in the middle of no where. When i woke the next morning, I had a phone number in my pocket. I called the number and the person on the other end sounded like a man and here name was Bosefis. This woman, Bosefis, could quite possibly, and most definetely be a Jumbo Schleechum.
Another way to say slob on my knob or suck my cock. When you are mad at someone just tell them to go Schluck on the schleet. Also what you say to someone that is a brown-noser.
