I think it's a Meme.
Referring to a stereotpyical user who makes dubious boasts about driving a Honda Accord. This mythical poster will also refer to increasingly unlikely feats, typically involving winning a fight against a famous person (eg. Mr. T, Chuck Norris).

The overall implication of its mention seems to be to imply that the original story-teller is spinning an improbable fantasy tale, in a vain attempt to make themselves appear amazing.

I was going to say I never knew Chuck was actually his middle name.
