Seconding Apples to Apples. But there may end up being more arguing and shouting than you want.
Rummikub is an absolute favorite.
Taboo is good, but tends to be loud, especially with team play.
You can't go wrong with a couple of decks of cards. There is a South American game that expands to fit the number of players. You need a deck for every two people playing. It's a type of contract rummy ...
Telefunken. I play the Ecuadoran variation.
I've lately been teaching my friends to play
Farkle. There are numerous variations on the rules. There are also numerous variations on the name. I learned it merely as "The Dice Game," have also heard it called "Fuck Me," "10,000," and "Greed." Equipment is simple ... six standard dice, paper, and a pen. You can buy Farkle sets that include a dice cup. I have one, but only because the game with the dice cup was cheaper than buying two sets of five dice.
there is a variation of Farkle called
Cosmic Wimpout that is also a lot of fun.
Classic games like Scrabble and Monopoly usually do well ... and I had fun recently playing The Game of Life with my friend's kids.
Front Porch Games has some really cool games, including Dread Pirate (not a fav but my pirate obsessed friends like it), and Valley of the Pharaohs (which I do genuinely enjoy).
