Unless you are on a bike where your back is perfectly upright, the weight will be shifted around very uncomfortably and with gravity and protrusions will dig into your back.
Of course 100kg is impossible either way. You could do maybe 30kg max. Even at 30kg the bag will probably rip after a few uses, since they're destined to carry relatively light food.
I've carried packs of 2L water bottles in them, that's about the max you could do.
TLDR you're a retard
