Puss

Someone explaining to another that what they did/said is cool. Excitement and acknowledgment that it’s cool.

Person 1 telling person 2: I went snowboarding and as I was bombing down the slope I noticed the rail in the park so I just went for it and perfectly landed and did a double twist before landing back down on the slope.
Person 2 replying: That’s puss! You gotta take me next time you go boarding
