When you’re positively surprised or caught off guard by something majorly impressive. Like when a particular aspect of your makeup is popping, or your friend has gone above and beyond for you.
Example 1: When you’re applying highlighter and it’s blinding AF, you’ll say to yourself: “Come through highlighter!”
Example 2: When your friend manages to get you the last pair of heels in your size, you’d say: “Come through, Helen! You saved my life.”
