What would happen if a stereotypical nerd tried to strangle me to death with his thighs? Would I be able to get out or would I suffocate?

Nerd example -
Let's say he wants to asphyxiate me by getting me in a scissor hold and squeezing down on my larynx and the back of my neck. Let's assume he's a normal sized nerd, and I'm an untrained guy the same size and height as he is. Would I be able to get out of it before I suffocate (takes about 10 minutes) ?
