weaponized incompetence: purposefully doing a task as badly as possible so you won't be asked to do that task again, i.e. washing new jeans with white clothes knowing fully well it will ruin the white clothes because you're sick of being asked to do the laundry

NOT weaponized incompetence: asking for help and/or clarification with doing a task, i.e. asking which clothes need to be washed separately and what settings different clothes need to be washed on
