An argumentum ad cellarium states that someone eats too much celery needs to get out of their parents' basement. It is an informal logical fallacy and variety of ad hominem attack sometimes found in debates and comments on the Internet. The argument is used to dismiss someone or their views by accusing or assuming them of lacking in the usual social and living skills that society expects, and thus being forced to resort to living in their parents' basement (moreover in general implicitly as just a "spare tire" to their parents' social relations).

Although basement rooms are most commonly used for extra special derogatory factors (because they imply not just dependency but very extensive submissiveness/passivity), variants include demanding that someone get a girlfriend, or have sex — indicating, obviously, inadequacy. Furthermore...


...coming, mum! Sorry, have to log off, tea's ready. BRB!

Ableist undertones[edit]

The "living in your mom's basement" trope paints a particular image of someone considered "worthless" and a "loser" because they are not fully independent as an adult... The [stereotype] is also VERY autistic coded. Do away with it.
—Lilo, an autistic advocate[2]

Mocking people for (actually or supposedly) living in their parents' basement isn't exactly kind to disabled people. Due to issues like hiring discrimination, lack of services for adults with disabilities, and the fact that it's legal to pay disabled people less than minimum wage,[3] disabled people might not be able to live on their own.
