Man, I remember back in midwest in early 90s in high school.
My best buddy (white) and I (asian) go to local Hyvee, local grocery store there like "Stop & Shop" in NJ, or "Publix"
You know, he wasn't really from the richest family either - actually he's the one who taught me how to eat poor man's instant Ramen Noodle (never had like that before - he would drain the noodle, and sprinkle a bit of powder package on top with bit of butter to melt & mix) - which became another college staple for me back then, as a struggling art student who spent most of his money to paint material, canvas etc & video games.
So we go to this grocery store for me to pickup some food to eat at my dorm (during summer, I took ESL classes in local university). While picking out bunch of long-shelf life stuff - I picked out SPAM, and he picked his favorite, Dirty Moore Beef Stew for his snack.
And we gazed each other and went "How do you eat that stuff! It's gross!"
I tried Dirty Moore Beef Stew upon his request, and it's not as gross as I thought it would be - but I will take SPAM any day over it. Seriously.
That was one of the biggest culture shock for me back then - that something I grew up loved by everyone around is considered a "gross" product.
Then some show on the cable showed this.
I still am triggered by it! LOL. Spam is good - in moderation, like bacon or anything else in life!
The jelly part, is little bit gross though.
