I'm not a huge fan of single word requests, but I don't think they should be closed for the wrong reasons, as this one was. The OP was looking for a word that describes someone with what we used to call a dirty mind, someone who saw double entendres where none were meant.
It was quickly closed as a duplicate of What is a good word to describe someone who is empathetic, quick, and witty in conversation?.
The top answers for the dupe were:
conversationalist, a wit, warm, charisma, gregarious and convivial, etc.
If I were a lawyer telling a male boss I would give him my briefs tonight, and he snickered for the fiftieth time, I would not really find that warm, charismatic, or particularly witty. I'd probably tell him to get his mind out of the gutter.
I don't care as much as some when questions are closed. I do think that in all fairness, though, we should do so for the proper reasons, both for the sake of new users who are often already perplexed by our close reasons, and to avoid the appearance of elitism.
Edited to add: I don't think we are elitist, or that most of our closures are bad (with apologies to phenry.) This could have been closed for a better dupe, for failing to meet the requirements of swr's, etc. Just not a "dupe" which is not a dupe.
