Cock combat ©
The male-male erotic practice of staging mock battles or competitions using the erect penis of each partner as "weapons."
Styles and rules vary:
Partners may stand with hands on hips, or grasping the penis at the base of the shaft; penises may be slapped together, rubbed together, or "rammed" vigorously; the testicles may or may not be legitimate targets.
The goal of the competition may be to force the other man to ejaculate; or to cause him to lose his erection; or, more frequently, simply to have fun and to finish with mutual ejaculations.
Though normally an affiliative and friendly, frankly erotic activity, penis-fighting between straight-identified males who are enemies can be, though still erotic, both painful and brutal.

Colloquial synonyms include cock battle, cock combat, cockfighting, dickfites, and swordfights.
Please note: not all Frot men are into penis-fighting.
Most are not.
But there is often, though not always, a playfully combative aspect to Frot.
