Abbreviation for "Moose Full Bag Release." In the Springtime, when the bull moose are frolicking and looking for females to hump, they've been saving up all their moose spunkz up from winter moose pussy abstinence, when they finally bust that first seasonal moose nut, it is, by necessity a Full Bag Release (FBR) of the bull moose (MFBR).
I was sucking off this moose yesterday in order to extract the spunkz to keep in the holding tanks in my back yard and was pleasantly surprised by the MFBR of the bull who clearly hadn't busted since last summer.
