Literally what the term says, when a man/trans-fluid person with his/her penis erectile puts heavy weights on it for sexual pleasure and stimulation, and as a flex to see how strong his/her cock is.
I put A block on a cock, well, more specifically, my trans girlfriend's cock to see how much stronger her cock is compared to my tiny little pimple penis. Oh she came so hard the cum blast literally lifted up the 50 pound block and that made my pimple penis cum as well, causing my penis to grow 8 inches with my cum alone. Damn what a dream
