Eponymic words are the idea that a person/thing/event can so embody a concept that it becomes a verbal shorthand for that concept. While often expressed as verbs, such names/words can also function as adjectives, adverbs, nouns, etc. This practice occurs from pop-culture inspirations as well as in-group references.
When this trope is in use, it'll be in the form of an indirect comparison, such as "You just pulled a (character-name)", "They (character-name)-ed a...", or "There's no (character-name)-ing ourselves now". The sentence subject is being compared to the character/item named.
More obscure references may be accompanied by an explanation, but don't count on it. Like any other made-up or obscure word, audiences may be expected to infer meaning from context. It's easier as a pop-culture reference (e.g. Macgyvering), and many of our Trope Namers were inspired this way as well. It's a normal function of language that exists purely because we love to tell each other stories.
May overlap with Pop-Cultural Osmosis/Pop-Cultural Osmosis Failure (when the name is from pop culture and another character understands/misunderstands the reference), Buffy Speak (when a character is using names because they don't know/forgot the words to explain it properly), The Catchphrase Catches On (when multiple characters use the same name in the same descriptive way), and Parody Displacement (when the phrase has been used for so long, people have forgotten it was originally a name).
Super-Trope to Brand Name Takeover (when a brand-name is used instead of existing descriptive words).
