Cupcaking

Cupcaking is internet slang used to describe when someone is being overly affectionate or flirtatious with another person, especially in a public setting. It often implies excessive displays of affection and can sometimes be seen as being cheesy or insincere.

Examples:

– Sarah and Josh were seen cupcaking all night at the party, constantly hugging and whispering sweet nothings in each other’s ears.

– I can’t believe how much cupcaking Linda does on social media, always leaving lovey-dovey comments on her boyfriend’s posts.
