Know every no
Because there's ten-thousand-and-one more for every one.
I encourage you to approach language—common, formal, etymologies, translations, linguistic registries, phraseologies and evolving usages unconventional or otherwise—with the same curiosity that made you interested in "attempts at socialization" so that you know all the more what, when, how, where and who deserves the succinctness, certainty and sterility of your no-slang-no-rhyme-clear-as-blank-stare "No" (without-a-blink).
Aversion is like allergy. It is powerful to know all that you are allergic to. (Literally saves lives).
Equally, it is powerful to understand that not all have the same allergy; some might be immune; and others might allergically react differently, yet are equally reacting in power of active aversion (tolerance).
Let fruit be fruit so that you know what you have strong aversion to and what you don't. Because fruit comes in beauty, desire, and joy (too). And you won't appreciate all the ways it can be put to use for the greater change you hope to see in your own friends—including ones that might be imploding with a smile unbeknownst to all of you (including you) just to avoid those very stares—if you (too) avoid every named and unnamed thing that reeks slang of ugly.
Let the human race be the human race, buddy. You know who you are and that "No" is a complete sentence so make sure nothing slips through its completeness each and every time you say it.
"A cucumber is bitter. Throw it away. There are briars in the road. Turn aside from them. This is enough. Do not add, "And why were such things made in the world?"
