A frontside 180 off a kicker means spinning with your chest opening toward the downhill side and landing switch. You should be comfortable with a straight air off the same kicker and have your flat ground 180 dialled before adding rotation in the air. Approach on your heel or toe edge, open your shoulders, pop off the lip, and continue the rotation to complete the 180. You land riding switch, so make sure your switch riding is solid first.
Frontside means the first 90 degrees of the spin opens your chest out toward the downhill valley. You can actually see the whole rotation happen, which makes this the friendlier 180 to learn first. Pick a spot to do the 180. This can be a roller, a jump, or just a spot on the snow in front of you. Approach on a soft heel or toe-edge carve, wind your shoulders slightly closed (toward the hill), as you approach the spot you've selected, start to open your shoulders. Then, as you pop off the lip, let the shoulders release and lead the spin. Your lower body follows wherever your upper body points.
The most common mistake is starting the spin too early, before the board has left the lip. That makes you spin on the snow, kills your pop, and usually causes a weird sideways crash on the transition. Pop first, spin second. A good mental cue: don't even think about the rotation until you feel the lip leave your feet. Then unwind your shoulders hard and spot the landing over your new front shoulder.
