Boyfriends like to play ambiguous jokes with other girls on the internet and talk about the Woods. He said it was a way for post-90s generation to chat and joke online. Is it reasonable?

Unreasonable, this is obviously flirting with other women.

Sometimes it's a joke, and it's true when you say it. This is called that the speaker is unintentional and the listener is intentional.

You can see from this little incident that your boyfriend is a restless person. He can do this in front of you when he is with you. If he goes behind your back, he may do something even more outrageous and even cheat. Because he has such an idea in his heart, anyone with a discerning eye can see it.

Be careful when you are with him, it depends on whether you will hug him in the future. If he really likes you, he would never do it, at least not in front of you.
