1st 

A demigod amongst mortals, 1st classmen are the rulers of their domain. With an assigned rat as their scribe and pupil, these fearsome men and women are untouchable to all but the commandant's staff. Some chose to go to the dark side and join the ever terrifying RDC, but some purified themselves and became the OGA, CEA, and chaplains. The bulk of their ranks are comprised of first class privates, these 1sts are the most laid back people in the corps and ultimately they make VMI run properly. The officers of the 1st class are the most disciplined cadets of the corps, but other than parade and ceremony they have little control over anything due to the overarching control of the commandant's staff.

3rd: "STOP RAT. Strain HARDER"

rat: *straining intensifies*

3rd: *Incoherent Bitching at rat*

1st: "Rat stop straining, get your chin in third. NO ONE STRAINS MY RAT LIKE THAT EXCEPT FOR ME, YOU GOT THAT? Now go back to eating your shit and be gone."

3rd: *scurries away*

1st 

1st is the 1st thing you think of when you want to recall what girl you like best.

In your mind you'd be like:
Well 1st girl i like best is Jenna.
Next girl you like best still isnt as great as Jenna is. So yep 1st, last and forever the only name i recall 1st is... Jenna.
Actuall

Jenna is always the 1st to tell it how it is to your face. And yet, rarely has she needed to do so because she can hold good coversations, has manners and knows when to shut up.

1st Noteable thought that comes to mind when i think of Jenna is that good friends are hard to find, difficult to leave and impossible to forget.

1st 

1st as surname was first used by person named 'Aman 1st' to signify as no religion, no caste, no race surnames without having to go through the frustrating process of dealing with corrupt, incompetent government employees to get such certificate. So you can use this surname as alias while maintaining the actual one in govt records.

In case some online form doesn't allow numerals than capital "I" can also be used e.g. "Ist".
