'Ship' and 'OTP'

So, most geeks, nerds, or whichever term you use to refer yourself as, the phrases 'shipping' and 'OTP' are used in our daily language. Most often we see these terms used for the Harry Potter fandom and even the Doctor Who fandom (which I have yet to become a part of, sorry to disappoint). As a manga and anime lover, I personally see these terms are countless social media that I am a part of. I have always used 'shipping' myself for many years, but the term 'OTP' was just introduced to me within the last six months. Confused, and in a sort of dazed confusion, I Google-d the meaning of this widely used phrase. So, I thought maybe I could help out anyone new to the fandom worlds by laying out the meanings of these two terms.
First on the list: Ship.

• a desire for two people within a fandom to be in a romantic relationship (often fictional characters)
• a general term used by fans in a specific fandom
• ONE rule - if one or more fans ship a pair it is therefore a rightful ship
• also - a cannon is when a ship turns into an actual relationship

(All information on the term ship found here)
Second on the list: OTP.

• similar to the term ship
• stands for - One True Pairing
• is often the result of the favorite combination of characters from a fandom

(All information on the phrase OTP found here)
Personally, I ship many characters together including:
   Natsu+Lucy (Fairy Tail)
   Erza+Jellal (Fairy Tail)
   Juvia+Gray (Fairy Tail)
   Gajeel+Levy (Fairy Tail)
   Makisa+Eren (Attack on Titan)
   Armin+Mikasa (Attack on Titan)
   Hikaru+Haruhi (OHSHC)
   Haruhi+Tamaki (OHSHC)
   Eclipse+Raenef (Demon Diary)
   Ichigo+Rukia (Bleach)
and many, and I mean MANY, more. Those are all just from manga/anime. But, over all, I have to say that my OTP has to be Natsu and Lucy from Fairy Tail (they're from the show that theme song is from...I linked it yesterday).
I'd love some feedback of who your OTP is and who all you ship! I don't mind a list at all! I am making a list personally of anime to watch and more manga to read, so if you have anything to recommend, leave a comment. If you have Google Playstore, I recommend downloading the app called Manga Rock, it's amazing!
