A swear replacer. Don't say a swear, use "nert". Teachers and parents don't know what it means so it makes it a way to beat the system.
My teacher was pissing me off and I screamed "nert" and she didn't know what it meant so I got away with it.

Get the Nertmug. verb: nerd flirting. When an individual of above to highly above average intelligence attempts to flirt with a potential sexual mate. This is commonly observed with bad jokes, awkward laughs, and a tendency towards conversations around Pokémon and Harry Potter. Nerting is generally most successful with another individual of above to highly above average intelligence as the cryptic social queues of the nerting protocol are more easily understood.
