The term "lump it" means to not do something or forget about it. Lump it replaces the saying "fuck it." However, lumping it gives you the same satisfaction as if you did the task at hand, even if you didn't perform such an action. "Lump it" can be used as a noun, adjective and verb, such as; Lump it, Just lump it, lumping, lumped or simply lump. The use of the phrase will soon come naturally. I would explain the definition more but lump it.
