The difference between COCK, DICK and PENIS

It's easier to write about Socrates than about a young woman or a cock - Anton Chekhov

According to any dictionary, the word 'cock' can refer to the male chicken, the male of any bird, a hand-operated valve, or a hammer. In slang dictionaries, cock refers to the same thing as 'penis', 'dick' and sexual relations with a man. We can also find the word 'cock' in some idioms, such as 'to cock a snook', which means to disrespect or to insult someone.

What's the difference between white onions, brown onions and a 14 inch dick?
Nothing. They all make women's eyes water!

Eh, a dick is not as subtle as 'cock'. In some dictionaries, we can see the word 'vulgar' right before its definition. So, we find out that pronouncing the word 'dick' more vulgar than the word 'cock'. Next, a dick can also refer to a guy. Yes, you usually insult a guy, by calling him 'A dick!'. The word can also be found in some idioms, such as 'tights as a Dick's hatband' which means 'extremely tight'.

The word can also be found in literature, such as the famous novel Moby-Dick, and in some countries like Croatia, where an entire city is called Dick. If you visit this city and people ask you 'How did you feel in Dick', this is however, not considered vulgar. Why? It's semantics.

A foot and a penis are talking to each other, and the foot says, "I have had it so bad in life. Everyday my owner sticks me into a smelly shoe and walks around on me all day long. My life sucks!"
Then the penis says, "You think you have had it bad. My owner sticks me into a deep black hole that smells like fish every night and then makes me do push ups until I puke!"

A penis is a penis. Any dictionary gives the same definition for it, so PENIS has the most obvious meaning between the three words. Once you pronounce it, you can no longer hide your head in the sand, because anyone thinks about the same thing. The word penis can also be found in the expression 'penis wrinkle', as a form of insult.
