Acronym for AND CIRCLE GETS THE SQUARE or ACGTS. It was a popular retort for scoring a point on the 1970's (and current incarnations) of the popular, quasi-celebrified game show Hollywood Sqaures. Now, more popularly used among the ironic set. Spoken or in print form. It should be used as an alternative to FTW and EPIC. Especially useful in ironic ejaculations.
