What does it mean to "charge"?

[abuse]

I used TFSE but did not find anything that answered the simple question of what it means to "charge" products in a vessel. A quote from a synth...

...and 300g of xyz were charged into a 250 ml three-necked flask...

I checked Zubrick but there was no mention of "charge" in the index. Is "charging" a fancy term for simply adding products to a flask?

My dictionary says (among other definitions):  to load or fill with the appropriate amount.  Perhaps chemists who prefer this term are more aggressive personality-wise than those who simply place or put a chemical into a vessel, LOL
