If you want specific subdomains that do not exist, well you'll just have to create them, and then redirect.

To catch all erroneous subdomains, say I accidentally type metaa.stackoverlow.com, use a wildcard: *.stackoverflow.com. In cpanel, this just involves ticking a checkbox that asks 'make wildcard?' or similar. To edit .htaccess directly, just enter * in place of each specific subdomain.

Note that this also applies for any directories:

subdomain.site.com/*

*.site.com/dir

*.site.com/*
