Used when someone gets told, gets shamed, something embarresing/bad happens to someone. Often said upon hearing another persons bad situation. Could be said instead of 'thats dread!' 'thats bad' or 'oh no!' or 'oh shit, he must be embarresed'
Person A: Aww did you hear what happened to Ben? His girlfriend cheated on him with a chick!
Person B: Feel it!
When you have just finished insulting or pissing someone off with something you say to them, this short phrase can be attached onto the end in order to tell them to "take it hard" and therefore adding more strength and power to the impact of the insult.
This is a phrase that can be added on to an insult, or a snap against someone's mama. It basically means to take something painfully or be hurt by it (what the person has had said to them), and increases the impact and effect of the insult by the user.
