Used pejoratively, the term "Rembrandt" can be applied to any lecherous individual over 40 with pedophilic predilections of any sort.
The term was originated in Germany in the early 2000s in reference to a highly suspicious park-dweller in Bonn who accosted a group of schoolchildren inviting them to a "night walk" with lanterns. The individual wore an ornate leather hat not unlike those in Rembrandt's famous painting "The Night Watchman."
The term can also be used more playfully to designate any individual (almost always male) guilty of ogling women under 18.
On June 15th 1985, a Lithuanian man entered the Hermitage museum in Leningrad, and approached Rembrandt's 1636 painting "Danae". He slashed and stabbed at the ancient canvas twice, then tossed a bottle of sulfuric acid at it. This event is referenced in the phrase "a burning rebrandt". Though acid was used to burn this painting away, anything that burns in anyway may be remarked upon as being a burning rembrandt, or as burning like a rembrandt.
An mentally unstable artist who is especially talented, but due to his chosenmedium (i.e. feces) will never be widely observed.
"Think of how many loonies will never be recognized because their art is made of blood and feces and is less enjoyable because of it. So many fecal-Rembrandts will die in obscurity." - singasongofsixpins
