--Verb--

(subject)^2√2

To raise one to the 2(root)2 power. It comes from the mathematical expression - the square root of 2, multiplied by 2.---(2√2) By raising a person to the 2root2, you put them to sleep. This action is specifically performed by foreign math teachers with heavy accents who repeat the phrase over and over again in a monotone, putting the person to sleep.

Note: this phrase is often spelled 2 rrrrroot 2,,,,notice there are multiple R's,,this puts more emphasis on the European accent.
Student 1: (sleeping)

Student 2: "Damn!!! She just raised yo ass to the 2 root 2!!!

2-methyl-2-butanol is a tertiary alcohol which is 20 times stronger than regular ethanol (alcohol). 2-methyl-2-butanol doesn't produce aldehydes as a metabolite and instead, produces 2-methyl-2-butanyl gluconoride and 2-methyl-2,3-butanediol. Meanwhile, ethanol produces acetaldehyde, a moderately toxic aldehyde, before becoming the harmless acetic acid. As a result, there is no hangover from 2-methyl-2-butanol but there is a temporary hangover from ethanol. The dose range of 2-methyl-2-butanol is 2ml to 12ml+.
2-methyl-2-butanol can be made from ethyl chloride by the grignard reaction from an ethyl magnesium chloride intermediate reacting with acetone and then a hydrochloric acid work-up.
