Cheeky little monkey (my cheeky little monkey)

You look like a monkey

Thank you in advance if you can help

My attempt for my cheeky little monkey

benim yüzsüz maymuncuk

not sure if the monkey (maymun) should also take a possessive ending to become 

maymuncuðum

or maybe use

yüzsüz küçük maymunum

you look like a monkey

bir maymun benziyorsun

Wait for native speakers or you might offend your friend!!!

 X2.  There is no telling if that expression makes any sense  in Turkish(or isn´t just insulting)!

Cheeky monkey is ´Yüzsüz maymun´ - but as some quite common expressions in English are considered a bit insulting in Turkish - as they said above - I would be careful if I were you!

I think telling someone they ´look like a monkey´ would be considered fairly rude in any language though!

yes it is not nice to use the literal translation " yüzsüz küçük maymunum" in Turkish.

maybe native English speakers may help saying in what situation they use it and we can find such a thing that we use

i heard that it is used for people who pretend to know it all, and then you can say "çok bilmiþ seni!". but as I have said I am not sure about its meaning.
