A rare and abnormally large bowl movement with signature length or girth or quantity because it resembles an Elk dropping.

An elk-loaf is often considered a masterpiece and thus frequently not flushed by the artist, so it's often associated with people prompting each other to go and view it.
1. Guys, I just laid an elk-loaf in there... I didn't have the heart to flush it.

2. Someone left an elk-loaf in the men's restroom... stall #2. You gotta go in there and look, that thing is enormous. I bet a 450 lb. person must have laid it.
