It's a lesson some fellas could do with learning: As proud as you might be of your crown jewels, they do not need sending to people who don't ask for it.
One overly-amorous Debra Messing 'fan' (read: creep) has found out the hard way (no pun intended), after the former Will & Grace
star shared an explicit picture he'd sent her with the world, telling him not only to "respect women", but to respect himself too.
The 47-year-old Mysteries of Laura
actress was having a quiet Tuesday night when suddenly she was confronted with a surprise of the one-eyed variety.
But it wasn't all.
Deciding to make an example of the creep in question, the 47-year-old decided to share the picture to her 250,000 followers, with the caption: "Sending pix like this is NEVER OK".
She added: "RESPECT WOMEN. RESPECT YOURSELVES",
Responding to a woman who said her male friends told her to accept such behaviour as "part of being pretty", Debra called bullshit, arguing that no one "invites" explicit images and harassment without their say so.
And while some criticised her for giving the man in question "exactly what he wanted" - i.e. world recognition of his 'very large' penis - she refused to give him any kudos.
Finally, after it all died down, Debs proved she could read us like a book.
