I tried that hover bit, something I have picked up off of using Discord on the smartphone, but in many cases, while a label was attached, the actual meaning was unclear, as is true of a lot of slang. Normally you can decipher slang words via what that word or phrase is embedded in, looking for context, but for simple "the sentence is the emoji" bits, that was not available.
