In British and multicultural London English, 'bare' before a noun or adjective means 'a lot of' or 'very'. 'Bare people' = lots of people; 'bare jokes' = very funny. It has nothing to do with nakedness in this use. The word migrated from Jamaican Patois into UK youth speech in the 2000s and is now standard among British teens. If your child says 'there's bare homework' they are complaining about the quantity, not commenting on its state of dress. Informal and harmless. Common in grime, drill and everyday British chat.
