Duncan McJunkin 

1. A euphemism for penetrative intercourse. The meaning of "McJunkin" being an thinly veiled reference to the male anatomy, "Duncan" provides the contextualized action to its complement.

2. Also my real name.

3. How is this not the title of a world-class porno?

She's up all night to the sun, I'm all night to get some, She's up all night for good fun, I'm up for Duncan McJunkin.

Have you met Duncan McJunkin? He's an important political leader, in the echelon of Richard "Dick" Swett.

A celebrated male porn star, Duncan McJunkin's cameo role as the plumber in "Pipe Cleaners" was an apt use of his talents, but was hindered by a lackluster and flaccid performance by his costars.
