does foul play get a boost from life orb or it doesn't because it's using enemies attack instead of yours and if it doesn't or does, can it take away your health or not?
I didn't find this online, so I tested it on PS!
And YES, it does.

This is because even though you use the Opponent's Attack Stat, it is your Pokemon that is using the move. [1]: http://replay.pokemonshowdown.com/ou-221289853
