When someone does something you don't like and/or makes you mad and you want to punch or slap them. Raising fists while saying this for optimal results.
If a guy says it it means are you trying to fight/do you want to fight but if a girl says it (to a guy) it means do you want me to give you a hand job basically
Guy: you trying to catch these hands
Other person: yeah come at me
Girl:you trying to catch these hands 😏
Guy: defiantly 😉
