(t p -skwot ting) slang.
Purchasing a domain name that is a variation on a popular domain name with the expectation that the site will get traffic off of the original sight because of a user’s misspelling of the name. For example, registering the domain names webapedia.com or yahooo.com in the hopes that someone making a typo will get to that site unexpectedly.
