After seeing that new pic my guess seems silly.....!!!
Your weight should be a good 111kg!!
Congratulations! You are by far the closest and almost the only person here who guessed a triple digit bodyweight.
When I weighed myself Thursday I was 109.7kg, I fluctuate around the 108-110kg region.
Obviously as I don't walk around topless, then the impression I leave is the one that you get when you see me in a shirt. I can understand the underestimates on the internet due to having no frame of reference to compare me against something, however as I said people whom I see in real life also all underestimate me.
I seem to pack on muscle into my thighs really easily, back too somewhat, but these are not the traditional chest-arms areas that most people associate with high muscle mass which is where I am lacking. Most people who weigh anywhere near I do have arms far thicker than mine which due to the upper body focused world we live in makes them seem bigger.
I would have guessed around 100kg as well. He is tall, looks slightly soft and has obvious thickness and a bigger bone structure and a reasonable amount of muscle, even if the overall effect whilst clothed looks soft, but extra fat only adds to your total weight even if the net effect is to look less muscular.
I think the morale of the story is that most people are absolutely rubbish at guessing peoples weights whilst clothed...you can make most people look either fairly jacked or fairly skinny just by changing the sizing and fit of the clothes they wear because you can only really judge relative to the clothes when fully dressed unless you have a good eye and some experience with estimating these things.
