A bet that pays off big or just something that is awesome. Comes from the racetrack, where a winning bet on a big ticket pays so many zeros that it looks like the dots on double sixes ("boxcars" in dice). Can be used in combination with ship it.

Derisive term for a sizable number of acquaintances of someone with a dubious reputation who make praising statements about the individual's character/morals, offer to co-sign a loan he's requesting, etc., but who are of comparably-questionable integrity themselves, are also broke, etc., and so their own word and/or reliability is viewed as not being much more of a legitimate guarantee than the promises of the person they're vouching for. In other words, "quantito, but not qualito"... lots of impressive-looking "containers", but with no actual/tangible/legitimate "goods" inside of said containers.
Loan officer: I always feel really wary/suspicious whenever someone of unknown/questionable reputation asks for a loan and offers to bring in a number of other folks to vouch for his character, reliability, and financial responsibility --- "methinks he doth protest too much", plus usually his so-called "witnesses" appear to merely be an "empty-boxcars train of assurers"... they seem no more trustworthy than I would view the loan-requester himself as being, and so their voluminous praise/recommendations hold little significance and inspire little confidence in me regarding whether the loan-requester would actually possess adequate means/motivation/dedication to repay the money. I feel something like how the lady-attorney in "Losing Isaiah" did when she pointed out that the members of the "support group" whom ex-druggie/shoplifter Khaila had named as the people who were assisting her in her efforts to "go straight" and "live clean" had themselves all been former drug-users and/or criminals, and so she felt that they should not be considered to be viable/reliable helpers to prevent Khaila from relapsing.
The ability girls and women have developed to hold several items at once in one hand. The skill has been developed due to the lack of pockets in women's clothing.
I thought she'd need multiple trips to carry her phone, keys, wallet, and Starbucks to her car since she needed the other hand to open the door, but she used her impressive girl grip to carry everything in one hand.
