Opposite of a Dick move. Doing something nice to others with pure intentions. When someone does something that makes you want to pat their head and say "Good boy".
- "That guy just gave me part of his sandwich because I didn't have any food."
- "Wow, what a good boy move."
Short for good luck mate. Derived from the expressions "gl", meaning good luck and "m8", being short for mate.
While texting:
You - "I have a math test tomorrow"
Friend - "gl m8"
