Overlook it, it's not important; you're quite mistaken. This colloquial imperative is used in a variety of ways. For example, in Thanks so much for helping-Forget it, it was nothing, it is a substitute for "don't mention it" or you're welcome; in Stop counting the change-forget it! it means "stop doing something unimportant" in You think assembling this swingset was easy-forget it! it means "it was not at all easy"; and in Forget it-you'll never understand this theorem it means that the possibility of your understanding it is hopeless. [c. 1900]

Overlook it, disregard it. This colloquial imperative, dating from about 1900, is used in several ways. It can mean the same as “don’t mention it” or “you’re welcome,” as in, “‘Thanks for picking me up.’ ‘Forget it, it was no trouble.’” It also can mean “it won’t happen” or “it’s impossible,” as in “Find a parking space near the theater? Forget it!” These same meanings can be conveyed by forget about it, which, however, also may mean not to recall something and is not a cliché.
