On behalf of parents listening to their children's youtube videos, we beg for mercy. Please, dear lord dear god, stop saying "smash that subscribe button."
First of all, no one is that enthusiastic about your acrylic muffin painting, or whatever, that they're like, "I MUST VIEW THIS AT THE EARLIEST OPPORTUNITY EVERY TIME."
But also, just, please don't use the word "smash." You sound like a frat bro lying about his weekend. It's like the manic pixie dream bro catchphrase. It implies that, at some point in your life, you have or will someday wear a visor upside down unironically. You sound like you count wearing a polo shirt as "dressing up."
Say "slam," like a civilized human being.
