What are some subtle signs of Marine posers?

Well how about you give us an example of what you have seen so that we don't have to play your little guessing game all night? Obviously something made you ask this question.

I agree. No self respecting Marine would type out "Marine Corp"

A corps (/ˈkɔər/ "core"; the plural is spelled the same as singular but pronounced /ˈkɔərz/ "cores"; from French, from the Latin corpus "body") is either a large military formation composed of two or more divisions, or an administrative grouping of troops within an armed force with a common function, such as Artillery or Signals. Corps may also refer to a particular unit or a particular branch of service, such as the United States Marine Corps, the Corps of Royal Marines, the Honourable Corps of Gentlemen at Arms, or the Corps of Commissionaires.

What he's saying is that it's drilled into them how to spell their branch.

Another is that he might show excessive respect to the colors and insist that everyone around him do the same.

A Vet will stand and render respect, but not force some dooshbag to stand.

Spell Marine Corps "Marine Corp"

Most obvious flag right there. If you use the abbreviation for corporation in the place of corps, you're an idiot and you were never a Marine.

NOW THIS AIN'T NO SH!T........you can smell the methane. Most marines would not type like this to describe their beloved corp....end of lesson....ARE WE PHUQING CLEAR?

So WTF is your point kid.....looking for help on how to be an a$$hole...ya don't need it!
