When I learned to fly (at Jandakot, WA), it was called "crabbing". Of course, just prior to touchdown, you'd straighten up and drop the windward wing down and land on that wheel first.
A slip is a maneuver used to decrease altitude quickly while maintaining lower airspeeds. (Full rudder in one direction). Useful on approach. Crosswind landing is similar to a slip, it’s banking into the wind then using opposite rudder to straighten the aircraft out to prevent side-loading the landing gear. Using aileron to stay on centre line. If you have a control front wheel, you need to neutralize rudders just after touchdown, then use them to steer.
You'd want to bank a little bit into the wind to straighten the angle of your airplane relative to the runway; just before touchdown, instead of landing while still crabbing or slipping. That will reduce the risk of skidding on touchdown and having to make large rudder inputs while to try to keep it on the centerline. Boldmethod has a great video on crosswind landings if you want to dig into it further.
