I’ve been afraid to ask this even though it has happened to me several times in my life. I just laugh and try to alleviate the mess where I can.

Some of y’all in the comments are missing the “like I’m five” part of “explain like I’m five”…
To answer your question OP, water- or in this case, beer- *really really doesn’t like* bubbles moving around in it. If the bubbles are small or moving slow, it’s not so bad- but if there’s a lot of them, or they go really fast, the water can’t get out of the way fast enough, and the bubble gets “squished” as it tries to get away.
But when you squish a bubble *inside* the water, instead of a ‘pop’ there’s a little wave. That little wave can add up with other little waves, and lots of these little bubble-squish-waves hit the glass of the bottle *juuuuuuust* right, causing it to crack. Cracked glass is *really bad* at not-cracking-more, so those cracks get bigger until the glass fails.
All this happens *really super fast*.
