Being a ruben fall under these categories:
1. Not keeping it real with people.
2. Doing low key dirty shit and expecting others not to find out about it.
3. Doing low key dirty shit, forgetting you've done it, then play victim when others treat you harsh.
4. Calling others out as light weights when your actually the light weight.
5. Throwing little bitch tantrums.
6. Bragging about things that aren't true just to make people accept or envy you.
7. Pretending you don't have cash when your out with friends so they can pay for you when you actually do have cash.
8. Being a fucking douche when your (or supposedly drunk) to people because you think its cool.
9. Calling off a night with a friend you made plans with (REPEAT)...YOU MADE PLANS WITH (not they made plans with you) by pretending your sick, going out of town, etc; just to go out with someone else or a chick rather than keep it real and inform the friend that your going to do something else instead.
Anything that can be classified as a BITCH MOVE
1. Wow, I can't believe Gloria was being a ruben and didn't finish her Wine Cooler.
2. James threw out the line "I'm supplying the room" rather than help put in on food and drinks. We never done that to him when he comes to our room, what a fucking ruben!!!
