What that game called when you have o guess what the card is saying?

The game you're referring to is likely "Charades" or "Taboo." In Charades, players act out a Word or phrase without speaking, while in Taboo, players describe a Word without using specific related terms. Both games involve guessing based on clues given by teammates. If you're thinking of a card-based game specifically, it might be "Codenames," where players guess Words based on their team's clues.
