A gun made out of penis parts that shoot sperm bullets. They can be very dangerous if used properly.

small penis gun club 

Men who think guns are penile extenders. This club is especially for men who strap on their rifle's and assault weapons before going out in public. Members like to strut around with their guns, especially in front of women, falsely believing this makes them appear strong and attractive. Instead of appearing strong and attractive, however, members of this group appear to be overcompensating for their especially small penises.

Examples of small penis gun club members: The guys who hold gun rallies in mall parking lots, because four mom's demand action members are meeting inside. Other examples, Ted Nugent, Rick Perry, Rush Limbaugh

Penis gunk 

Penis gunk is when you haven’t washed your head for multiple days after cumming and are left with a cheddar like smear on the inside of your foreskin. This is not harmful but quite smelly,

Oh my god Brian. My doctor said I have type 2 penis gunk. He told me to tell my friends the dangers of not washing your head.
