After touchdown, most aircraft with spoilers will deploy these (automatically) to make sure the wings lose lift.
it never hurts to be able to pull a little handle and the wings magically loose lift while at the same time causing more drag than ussual.
A little clarification needed, I think. Spoilers are used after touchdown to force more weight onto the gear for braking, not for any other reason. It adds downforce to the airplane the same way a spoiler on a car does. It's not about drag (deploying spoilers alone is not going to do a thing to stop an airplane on the ground) and while it's technically about lift, it sounds misleading to say you'd deploy them "to make sure the wings lose lift" because it's not as if you're trying to prevent some sort of inadvertant takeoff, you're just trying to kill the lift so as much of the airplane's weight as possible reaches the landing gear to assist in braking.
But yeah, this is a takeoff anyway.
