DChen

A term created and popularized on the online community of AoPS, DChen is the name you give to a mathlete who wins the math competition ARML both individually and by being on the winning math team. Alternatively, due to stereotypes about mathletes, it has more recently been used to describe anyone on AoPS who is below the height of 4 ft 8 (see dwarves).

Man, I just won ARML this year as a team and individually. I totally just pulled a DChen.
