CHX-Br

CHX-Br is short for cyclohexyl bromide (or CycloHeXyl Bromide). Cyclohexyl bromide can react with sodium ethoxide (NaOEt) and ethyl acetoacetate (EAA) to form Ethyl 2-cyclohexyl-3-oxobutanoate. Then react with hydrochloric acid to get 2-cyclohexyl-3-oxobutanoic acid. Heating it up will get you Cyclohexyl-2-Propanone (CHX2P, Cyclohyxylacetone) , a useful intermediate in the synthesis of Propylhexedrine, and carbon dioxide as a side product. Propylhexedrine is good orally in doses of 60mg to 180mg+ to decongest the nose, as a pre-workout, and to lose weight. Cyclohexyl bromide can also undergo other chemical reactions such as turning it into Cyclohexyl magnesium bromide and reacting it with Propyl chloride to get 1-cyclohexylpropane (unless there's rearrangement to 2-cyclohexylpropane).

Tony: I synthesized Cyclohexyl-2-Propanone (CHX2P) using CHX-Br and ethyl acetoacetate.

TP-Br

TP-Br is 2-ThioPhenyl Bromide. TP-Br (2-ThioPhenyl Bromide, 2-thienylbromide, and 2-Bromothiophene) can be synthesized by bromination of Thiophene (TP-H, ThioPhenyl Hydride) with bromine in Carbon Tetrachloride. TP-Br is used as an intermediate to synthesize TP2P (ThioPhenyl-2-Propanone) by reacting it with ethyl acetoacetate and sodium ethoxide and CuI (Copper iodide) catalyst.

I synthesized TP2P using the TP-Br and ethyl acetoacetate.

Alguem Br

A phrase said by Brazilian online players when they join a game. Roughly translates to "Anybody Brazilian?" in Portuguese, with BR being an abbreviation of Brazil.

Similar to russian players who play CS:GO, unfortunately, players who say this are known to unwittingly throw the game due to lack of communication to the other English-speaking players.

Some players (who may not be Brazilian at all) may say this to troll other players.

*Red 1 joins the game.*
Red 1: alguem br
...
...
*Red Team has lost the game!*
Red 2: Red 1! You left us wide open!
Red 1: VocΓͺ nΓ£o fez nada! You did not do anything!

*Blue 3 has joined the match.*
Blue 3: Alguem BR
Blue 2: Oh god, if we lose this round thanks to this idiot...
...
*Blue 3 just team-wiped the Red team!!*
Red 1: Where the hell did this guy come from!?
Blue 3: HUEHUEHUEHUEHUE HUEHEUHEUEHYUEHUE
Blue 2: You lying jerk!! D8<
