The Turkish word? Sure, it is spelled as
sikim, where
sik [1] is the (quite vulgar) word for
penis (noun, when used as verb, means to f.ck), and
(i)m is the possessive affix [2]. The letter
i is always pronounced like the first
i in
victim, and the word is pronounced like
si-kim. The perception of the phrase is similar to that of
my cock, rather than
my penis.
One might think that the similarity is so vague, that wouldn't pose a problem to speak it out loud. I, personally never recognised the similarity, until I spoke the word out loud.
