Originated from a great song entitled "Lump" by 90s band Presidents of the USA, the slang term LUMP refers to anything good, bad or in between. For instance, lump may be used instead of gnarly, funky, cool, awesome or radical, for example "that hair-do is outrageously lump right now!". Despite this, the word may also be employed in a bad manner, replacing words such as cunt, fuck, titties, slut, whore or quite simply, "bad". YOU GO LUMP LUMP LUMP. It really depends on the context in which lump is used in, as sometimes this word may be misinterpreted. Be careful, lump is a valuable weapon capable of LUMP DESTRUCTION!!!!!!!!
You are looking reasonably lump today my darling ;) (used in a positive context)
OR
You god damn LUMP! (used in a negative context)
