look up any word, like vai tomar no cu:
A dump that is the by-product of eating too many White Castle burgers and holding it in for a couple days. A noticeable line, or merging point (hence the name merger dump) is present. This generally marks the point where two dumps join into one.
"Yo check out my Merger Dump!"
"Damn, three lines? You been holding that shit in for a while haven't you?"
