What is "lasse-maja"

Lars Larsson Molin, alias Lasse-Maja (5 October 1785 – 4 June 1845), was a notorious Swedish criminal who used to disguise himself in women's clothing, which gave him the female sounding nickname Lasse-Maja; Lasse is the common version of his own male name Lars, and Maja was a common version of the female name Maria. His nickname was a way of describing his ambiguous gender as well as the method he used in his criminal career.
