Really, anything is possible? Why don't you walk through a wall! Drink the whole ocean!
Now lets review the definition of a fluff hoping you aren't one.
Someone who claims impossible feats and spouts off impossible abilities and knowledge they claim to have but do not demonstrate in chat. When questioned about their claims or any attempt to give factual advice to them, said Fluff will become hostile and try to fight against the people who are only trying to help them, claiming they don't need help/already have the answers. Usually, a fluff will defend their nonsense with lines like "It's my belief" or "it's my opinion", "my friend said it was true", "nothing is impossible", or "I've done this before" (with no proof to back up their wild claims). A fluffy is someone who chooses to be ignorant by claiming fantastic things that are clearly not real, and should not be confused with someone who simply is uneducated. A fluffy acts immature, annoying, and derails intelligent topics with nonsense. A fluffy refuses to change their ways even when being presented with information to prove otherwise.
