Which counter and how to do it?

I'm not complaining I swear but I do feel like I'm losing my mind lol. I can't find the counter where you catch someone's fist/foot with a one liner. I saw someone do it playing journey mode on youtube and it only cost a skill point and it would help me immensely. I can't find it to save my life. I know I've done it a few times before but I can't find it in training and no video I've found has specified what it is. Playstation and classic controls. I can literally do everything else but that one for some reason lol.
