retronym 

.
Altering or adding to a prior word or term term that must be further defined in the light of later developments or technical innovation.

Example: No one called "World War One" that until there was a "World War Two" with which to contrast it. The going term during the 1914-1918 war and up to 1939 was "The Great War."
.
Other employment of term retronym:

Telephone becomes "rotary-dial phone" to distinguish it from the push-button phones that became widespread in the 1970s and early 1980s (although rotary-dial phones still work if all you want to do is place a call and don't need to access features like querying a bank account balance).

Similarly, telephone also becomes "corded phone" to distinguish the traditional hard-wired telephone from those that are wireless in some way, such as cordless phones.

"Regular" coffee to distinguish it from decaffeinated coffee; some people say "caffeinated" coffee but strictly speaking this is a grammatical back-formation, not a retronym, because "to caffeinate" would mean to ADD caffeine to traditional coffee.

Note, though, that Coca-Cola is a "caffeinated" or "caffeine-containing" soft drink in its usual red-can form. Now that there is a Caffeine-Free Coca-Cola "caffeinated" could find use as a retronym for "the real thing."

"Manual" or "standard" or "stick" transmission on a car, none of which terms was necessary before automatic transmissions on cars became widespread and assumed to be the norm.

And, of course, "acoustic" guitar.

Serial Monogamist 

Someone who jumps from one relationship immediately into another one.

Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.

Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
Person 1: Damn, Dustin already has a new girlfriend?! It's only been two weeks since he broke up with his fiance! I think he's a sociopath.

Person 2: No, he's a serial monogamist...
