Banger
Something that hits hard. Similar to something being is Killer. "Killer" is used more by people who go to the beach and have a relaxed vibe & acts like the word "immaculate" while "Banger" is more like standing out, explosive, and is more accurate to something being ideal, similar to the phrase "spot on".
"That's a banger coffee mug! Where'd you get it?" "This song's a banger! I can't wait to follow the artist after the music festival!"
