Hueco

Hueco, also spelled Weko, Wekereke and Huequereque, is a reclaimed slur used against men-loving men, transfeminine and AMAB gender non-conforming people in Guatemala, Chile and possibly other Hispanic countries. The feminine equivalent, Hueca, may also be used against sapphic women and transmasculine people. However, it is generally used to insult women as a whole.

Translation
The term "hueco" literally translates as "empty, shallow, hollow, or superficial" among other terms that indicate a lack of substance. This comes from the homophobic stereotype that queer men are usually feminine, and the misogynistic belief that femininity indicates no intelligence or dept within a person.

History
It is unclear when exactly the word hueco became synonymous with achillean, however it's been present on the internet since at least 2014. [4 ]
