Yes, just laugh it off. Think of how small it is in the big picture. Did anyone die? Did you hurt yourself in any way? No. Lots of people feel nervous during public speaking, it's a nerve-wrecking thing to do. But if you learn to accept the anxiety you feel and just shrug it off, you start caring less about stuttering/fumbling words, and focus more on how proud you are that you did it despite being nervous. Instead of being terrified that people are going to look at you weird because of what happened last time, just smile and make conversation about it. Tell people about how nervous you were, and that you wanna keep doing it so the fear subsides. Remember that courage isn't absence of fear, but feeling the fear and doing things regardless.
