Morphology

dirty + old + man

The meaning is largely derivable by combining 'dirty' (in its figurative sense 'lecherous') with 'old' + 'man', so the adjective-noun composition points clearly to an older man with indecent sexual behavior. However, it depends on knowing the non-literal sense of 'dirty' rather than literal uncleanliness, which some B1 learners may not automatically access, making the expression only partially transparent.

Etymology

Dirty old man The phrase comes from calling an older man dirty when he shows unwanted sexual interest or behaves in a sexually improper way, so the image is of an 'old man' with 'dirty' thoughts or actions. That's why it now means 'an older man who behaves in a sexually improper or unwanted way'.
