Get the UR MOMmug. 
This phrase is a very simple yet fatal combination of "ur" and "mom"; the word "ur" being an abbreviation of the word "your" which apparently wastes way too much of my precious time to actually write, so I replaced it with "ur".
This phrase is commonly used in the battlefield of roasting by fighters usually ranging of the ages of 9-12. This phrase is often used when you have run out of epic cards to play in your attempt of defeating your opponent in a roast battle which will change the course of the fighters future for a specific span of 3 minutes and 24 seconds max.
When using the phrase "ur mom" you are acquiring the power of the firmament and all the Holy power above and below the Earth, which surges your opponent with a hypersonic blast of pure awe and respect for your mere presence.
Those who use this phrase are often scrutinized due to the power in which this it holds and those who attempt to stop you from using this phrase, want to keep the power of "ur mom" to themselves, since they know the pure entity of greatness that such a phrase possesses.
