The numbers represent letters of the alphabet; 4 is D, 9 is I, and so on. These numbers spell "dick".

Dick. D is the fourth letter in the alphabet, I is the ninth letter in the alphabet, C is the third letter in the alphabet and K is the eleventh letter in the alphabet.
I prefer an uncircumsized 4-9-3-11
