Microphallus 

1. A penis smaller than GW Bush's brain;
2. A clitoris on a man;
3. A dick that is at risk of getting caught in your teeth;
4. A dick that is so small you have to punch yourself in the stomach to see the head pop out.

1. Damn, Lisa caught his microphallus in her braces;
2. His microphallus was so small he could nose-fuck her;
3. Is that a "AAA" battery in your pants?

MICROPHALLUS 

an abnormally small runion; a minuscule
penis.
Adjectival Variant: Microphallic

In a valiant effort to add length and girth to my microphallus, I did just as my friend suggested -- I tied a 20-pound dumbbell around my member and tossed it out the window. In retrospect, I think the suction pump might have worked better.

shemoose (italianus microphallus) 

An aging never was who believes that women in chatrooms find him "sexy",
he exists on playing eat the mud pie and mayonnaise sandwich with his neighbors 12 year old son. It has also been said that he funds his lifestyle by selling used cars and playing glory hole with his mother for 5 dollars a shot. His hobbies include slamming his ''big ITALIAN meat'' in a desk drawer to prove that tough guys don't cry and he ain't no pussy fag, and singing Barry Manilow karaoke while wearing a t shirt that reads " Beat me up I'm WICKED GAY!''

We regret that we cannot and will not give an example because it was just too fucking stupid to type.

The way this Acer Macrophyllum hangs from the cliff by the fingers of it's roots is poetic.
