A better version of the "Shut the front door" phrase, which eludes from the real phrase of "Shut the fuck up". This is a nice way to change the topic and be funny at the same time.

The act of bored children knocking on a door, and reciting the alphabet, which ever letter they get to when the occupant opens the door, is the first letter of the Person they MUST ask for.
No real purpose but to impose serious embaressment on the knockee.

A Door-County-gasm is one of the cumgasms a guy has when he's vacationing in Door County and eats some pot-stickers, gets into an outdoor jacuzzi on a moonless but glittering star-lit night and suck your buddie's dick underwater while he jacks you off with one of your knobby fleshlights until you're almost ready to cum, -- then he pulls it off your cock and you blow your load into the fleshlight, suck it out and sno-ball it, and then you swallow it and do it again.
