It's an adjective that means "extremely good or successful" according to Merriam Webster. It can also be used as a noun meaning simply "a success" according to my top Google results.
What I can't find is anyone who actually uses this word anymore, and I'm not going to start. At least it has a more positive connotation to its name than another, similar candy bar, that's perhaps a tad more famous and ubiquitous, named after a verb that means to "derisively sneer or laugh" at someone or something. Maybe it's not itself when it's hungry.
Well, alright, alright...what's the difference between a Trader Joe's Boffo! Bar and a Snickers? Hrmm...peanuts, caramel and nougat enrobed in milk chocolate. Could describe either adequately. Well, they're different...hugely different...and definitively, absolutely not the same, and Boffo!s (Boffos!?) are not pulled from the reject pile at the Mars factory...
Don't believe me? Fact check: Boffo!s weigh 1.8 ounces, as opposed to Snickers weighing 1.86, and as a result, have 10 less calories. So ha!
Repeat buy? Maybe. There's a time and place for an easily accessible, quick appetite smusher that sometimes involves the TJ checkout line. But compared to other of TJ's fine candy bar selections, this one is decidedly more utility than luxury. And I'm not a huge Snickers-type guy either...I mean, I'll be shameless when taking the "daddy tax" out of my kids' trick-or-treat bags, but there's plenty others I'd reach for first. Like Butterfingers...Anyways, it's 99 cents which seems to be the going rate for candy bars these days. Nothing too strong to say one way or another - not TJ's strongest performance, but nothing to make too much jest of, either. Check the nutritional stats here.
Bottom line: Trader Joe's Boffo! Bar: 6.5 out of 10 Golden Spoons
