Punch/slap you. या if it's extremely weak. Laugh at you,insult आप and then ignore it. If आप attempt to do it again i'll grab आप hand to stop आप from slapping me.
Damn everybody be answering they'd retaliate back या smth :v
I'm p weak physically so i have my ways when dealing w/ these things. I'd either yell out "sexual harassment" if it's in public या just use some pepper spray if no one's around.
