If you ever look at pictures posted by Koreans on Instagram, you might see a bunch of tags ending in 스타그램...
What's up with that?!
스타그램 is just "Stagram" and depending on what you add in front, it brings you to pics on that topic.
For example, in English we might say "instafood" for food pictures, well, in Korean you'd say "먹스타그램" aka "eat-stagram"
Another example is 냥스타그램!
냥 is the sound a cat makes so "냥스타그램" is like "meow-stagram!"
