text: It’s a conjunction that many MySpace people use, which results in a truly horrific sentence.  It is pronounced “and and” and originated with programming languages, which use this command for short-circuit logical operations.  That said, the proper use of && (if so be one) would function much like the dash—this is the longer hyphen and demonstrated herein.\n\nThe ‘trendyXcore’ kids tend to misuse this punctuation by inserting it everywhere an ampersand is present.  It is not functional as such and is better used to replace a dash.
