My friend said there was a case of this happening a couple years ago, where a smart, 14 year old boy suddenly snapped and killed a kid by crushing his windpipe and larynx with his legs and the kid struggled for like 5 minutes, where he then passed out, blood came out his nose and mouth and he died (RIP man if its true) I really don't think one could..i hate nerds but the ones I see at school have long legs but they are VERY thin, and weak looking so I suppose a nerd's legs would break before that could happen.
