Yes :D 'bout is a contraction of about. The apostrophe (') represents the missing vowel 'a'.1st:
is that 'bout an abbreviation of 'about'...so I can connect with the context "Now I've Been Sittin' Reminiscing about The Way We Used To Be "
Check is short for Check it , which is short for Check it out, meaning, look here, look at this, or listen here, listen to this.2nd:
check it in many E-songs..we can often hear it..like in Nelly's song 'ride with me'
Hmm. I believe it's short for reeling, meaning spinning, like spinning out of control in love. When in love, the world seems to spin around faster.3rd:
Because We're Reelin' what does this sentence mean?
All the best,
