Sometime ago I watched an RSD video which highlighted the use of sneaky keywords that acted as negs in conversation (I believe it was RSD Todd, which may explain why I can't find it again).

Ex/ Using "actually" before a compliment.

"You actually look beautiful."

Hamster -> "Why would I not look beautiful?", "Why do I only look beautiful in this instance?", "Did I not look beautiful before?"

Ex/ Calling her "Dude".

Hamster -> "Why is he calling me 'dude'?.", "Does he only see me as a friend?", "Am I not attractive enough to be a sexual partner for him?"

As I recall there were a few more keywords. I was just wondering if anyone would be able to elaborate on this or add other keywords, as I'm unable to find the original source.
