This is pretty straightforward. Take a bodyblock hit while the killer is transporting one of your fellow survivors.
The achievement goes with Kimura Yui's new perk breakout. With this perk you get faster while close to a killer carrying someone and the transported survivor gets a wiggle speed boost.
You don't necessarily need to play Yui to get the achievement or use the perk at all but it is a pretty fun one to play around with.
All that being said just go out and get hit by killers carrying your friends. Do it 30 times and your good to go.
