If you were a human on the Internet in the last 24 hours, you probably saw something about Leonardo DiCaprio's sneery reaction to Lady Gaga as she sashayed by him to go accept her Golden Globe. When Entertainment Tonight pointed out the trending moment to Leo backstage, he explained that he was simply surprised, and:

I just didn’t know what was passing me, that’s all!

Did DiCaprio think it was maybe a bear or a scary theater ghost, so he needed to laugh and give it "I'm not afraid of you!" eyes? Or did he mean it like, "I didn't know what was passing me by," like he suddenly realized that he might be missing out on life by not dating women over the age of 25? The world may never know, at least not until Entertainment Tonight corrals him backstage again.
