A lunar eclipse is when the Earth's shadow blocks the full moon, making it look red and dark.

A lunar eclipse is also when you're mooning (exposing your butt to) someone in broad daylight and a plane blocks the sun for a few seconds, casting a shadow on the moon (butt).
It was nighttime and all the people came to watch the lunar eclipse (Earth's shadow blocking the moon for a while).
Tom was mooning people and then a plane passed by to cast a shadow. It was a lunar eclipse (shadow blocking butt).

Ethyl chloride (EtCl, Chloroethane), is a chemical compound with chemical formula CH3CH2Cl, once widely used in producing tetraethyllead, a gasoline additive. It is a colorless, flammable gas or refrigerated liquid with a faintly sweet odor. Ethyl chloride is a lab solvent and an intermediate in the synthesis of 2-methyl-2-butanol through the formation of the grignard reagent, ethyl magnesium chloride and a grignard reaction with acetone, followed by hydrochloric acid work-up to yield 2-methyl-2-butanol. Ethyl chloride is synthesized by reacting ethanol with hydrochloric acid and zinc chloride catalyst. Ethyl chloride can also be used along with calcium hydroxide, sodium hydroxide, or potassium hydroxide to extract freebase arecoline out of the betel nut. Then react it with HBr (Hydrogen Bromide) to get Arecoline Hydrobromide.

I reacted ethanol with hydrochloric acid and a zinc chloride catalyst. I got ethyl chloride. I then extracted freebase arecoline from the betel nut and reacted it with hydrogen bromide gas to get Arecoline Hydrobromide.

I took some ethyl chloride and added anhydrous diethyl ether and magnesium turnings to get ethyl magnesium chloride. Then I reacted the Et-MgCl (ethyl magnesium chloride) with acetone. Then I took the 2m2bO-MgCl (2-methyl-2-butoxymagnesium chloride) and reacted it with hydrochloric acid to get 2-methyl-2-butanol.

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.
