goofball
A playful, silly person who makes others laugh.
A goofball is someone who acts silly, playful, and a bit ridiculous in a way that makes people laugh. The class clown who makes funny faces during lunch, the friend who does exaggerated dance moves just to crack everyone up, or the dad who puts on a goofy voice while reading bedtime stories: these are all goofballs.
The word has an affectionate feeling to it. Calling someone a goofball isn't an insult. It means they don't take themselves too seriously and aren't afraid to look silly if it brings joy to others. A goofball might trip over their own feet, tell terrible puns, or wear mismatched socks on purpose just to get a reaction.
Goofballs often help lighten the mood when things feel tense or boring. When a long car ride gets tedious, the goofball in the family starts singing silly songs or making up ridiculous stories. When everyone's nervous before a big test, the goofball cracks a joke that helps everyone relax.
Being a goofball takes a certain kind of confidence: you have to be comfortable being laughed at, not just laughing at other people.
