Noun. The line between the layer of melted marshmellow and the rest of the hot chocolate - clearly visible in a clear mug by a marked change in color, but otherwise determined by a sudden and marked change in temperature
Be sure to sip that hot chocolate slowly - if you cross the marshmellow barrier you'll scald all the way back to your tonsils.
