URAFI 

URAFI is an acronym for "yoU aRe A Fucking Idiot".

This can also be used in the form of a question by changing the order of the first two letters as in:
RUAFI?

Often that usage is rhetorical.

This phrase is sometimes used on neowin.net to avoid the swear word filter and to skim the radar of the moderators who look for personal attacks.

nobelium uranium 

A masterfully crafted response to the famously deadly "you mom gay" roast.
Believed to be forged by the finest of roasters, possibly even a level 3 sound cloud rapper.

Nobelium & Uranium are both elements. Nobelium's symbol is "No" and Uranium's is "U".
Combined, they make the response "No U".
Not only is "No U" an effective reply to any roast, but in this form it reflects your intelligence and can make their stupidity known, amplifying the affect of the response, ruining their career if used effectively.

12 year old COD gamer: "yo'ure mom gay"
You, blessed with an IQ of 5000: "Nobelium Uranium"
12 year old COD gamer: "Wtf bro"

Fluorine Uranium Carbon Potassium Bismuth Technetium Helium Sulfur Germanium Thulium Oxygen Neon Yttrium

The symbols of these elements spell out "FUCKBiTcHeSGeTmONeY." Alternate ways to do this include replacing Helium (He) and Sulfur (S) with Hydrogen (H) and Einsteinium (Es), and/or replacing Bismuth (Bi) with Boron (B) and Iodine (I). Some people have been clever enough to use this as their yearbook quotes.
