Pine Sol? What's it used to cover up?

Cuz this weekend, my neighbor used massive, i mean MASSIVE amounts of pine sol. The smell seeped into my apartment and stayed there for 2 days. I mean it was STRONG. So, like, does he smoke weed or something and is pine sol a commonly used scent to get rid of the smell or somethin?

Pine Sol? What's it used to cover up?
pine sol is a very strong cleaner,they could be using it to mask odors,like meth labs,dead bodies. or they just might be clean?
