There is this repetitive and predictable act which is passed off as 'humor' where people imply that what someone else said is meant in a sexual manner. Examples: saying 'giggity' or 'that's what she said' after someone says that an experience was really hard.
This always bothered me but I only just figured out why: it's a violation of consent (unless you know for sure that the person doesn't mind). A mild one, comparatively, but a violation nonetheless: you are symbolically forcing someone to talk about sex without checking to see if they would be okay with that. You are assigning meaning to someone else's words that you know they did not intend. You are not engaging in a mutual act of creating a funny moment: you are laughing at someone else's expense.
In fact, most of the people* I have seen do this only enjoy it if it makes the target uncomfortable. More often than not when it is done around me there is an attitude of attempted sexual dominance. If you do not laugh when someone does this to you, they will react as if you have taken something from them. People will react in ways that show this is not consensual and attempt to play it off as okay; they say "I walked right into that." Conversations should not have traps that one has to avoid.
I can't stand it when people do this, to the point that I never use the word hard when I mean difficult unless I trust the people around me not to do this. I will avoid ever talking to people who do this regularly. I will do verbal gymnastics to avoid someone shoving their empty, unfunny, worn-out joke into my mouth for their enjoyment. It's not cute and it's not funny.
From now on if someone steals my words and assigns sexual meaning to them, I will say, "please don't do that" and when they say "what?" I'll say "don't assign a different meaning to what I'm saying." or I may just say, "don't twist my words" depending on how annoyed/bold I am feeling.
*some people just love making people laugh and do this word-twisting in an attempt to be funny without realizing the effect it has. I can understand that. I have made such jokes before, feeling vaguely uncomfortable as I did so but dismissing it because I couldn't figure out what the problem was. Now that I have, I will not be doing it any more.
