To make a motion with one's arm, typically the right arm, that looks like scooping up a scoop of ice cream. Typically accompanied by a very corny expression to indicate sarcastic over enthusiasm.

To execute the perfect Dive-Scoop:
1. Make a loose fist, like holding an ice cream scooper

2. Bring it all the way down in an upside down "C" formation

3. Bring it back up, with a bent elbow

4. Deliver the withering corny 50's like smile (it should look a lot like the iconic "How about a nice cup of shut the f*ck up?" picture)
