Mantime is when fellow men, boys, and the male gender get it on.

For example, the conductor of the definition, Shrekungus, did Mantime with his fellow colleagues by fapping to burgers and guitar, eventually following with Netflix and Chill.
Dude, did you hear Ben and Izaiahs last Mantime (v. Shrekungus) session?! They are now in the hospital after that!
