An internet term that refers to Saudi Arabia's anxiety about sexual conduct.
The internet mispelling is a derived from a shortened version of the word asexual.
The "A" in front of Acex refers to "Arabia"--as well as asexual reproduction--while "sex" is mispelled to add to the effect of Saudi Arabia's ignorance of all things sex related.
