This word has three really important meanings. It's probably best if you remember them all. Let's do this!
When you're a guest somewhere it's important to bring geoducks. But more than that, the amount of geoducks you bring is really what matters. If you don't have any live geoducks go ahead and bring any amount of framed pictures of geoducks instead. If you can't even do that, well, then you're going to have to tattoo geoducks on your forehead.
Unfortunately, if you mess up any of these things, (the amount, the framed pictures, or the forehead tattoo) every other guest will gawk (がく) at you.
