Lolicon is the combination of the words Lolita and complex, and is used in the otaku community to refer to a genre of anime and manga, where a loli, or underage girl (normally under thirteen) is featured in a sexual context.
The same genre with a male protagonist is called shotacon, which is widely popular among female otakus.

It was used in Japan during the 1970’s and was used to term fan art about young girls.
Lolicon is an expression mostly heard around weebs and otakus, who are – for some reason – aroused by underage girls.

The first Urban Dictionary entry was added about lolicon in 2007.
Delicious Flat Chest or DFT for short is a meme in the anime community that is related to lolicon.
