Penis fighting
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, cockfighting, dickfites, and swordfights.
Please note: not all Frot men are into penis-fighting.
Most are not.
But there is often a playfully combative aspect to Frot.
And the idea of the combative aspect of phallus against phallus, of a phallic Man2Man contest, even if it's only expressed in the usual phallic rubbing, is very powerful among Frot men.
As it is among many Men who may not even know the word Frot.
For example, there's a common game among straight-identified guys called "Battleship."
In which two guys jerk off facing each other.
To first to ejaculate and cover his opponent's cock and balls in his cum -- wins.
