Adult card game Cards Against Humanity announced Tuesday that it has purchased a piece of vacant land on the border of the United States and Mexico to prevent President Donald Trump from building a complete border wall.

The company announced its effort on Twitter and an official website called "Cards Against Humanity Saves America." The company said it has spoken to a law firm specializing in eminent domain and promised to make it difficult for Trump to construct the wall. 

"It will be fun, it will be weird, and if you voted for Trump, you might want to sit this one out," the company said on its site.

Customers who send $15 to Cards of Humanity will receive "six surprises" in the mail, including a map of the land they purchased. However, the promotion is limited and will be awarded to the first 150,000 people who sign up.

"Donald Trump is a preposterous golem who is afraid of Mexicans. He is so afraid that he wants to build a $20 billion wall that everyone knows will accomplish nothing," the website says. "We've purchased a plot of vacant land on the border and retained a law firm specializing in eminent domain to make it as time-consuming and expensive as possible for the wall to get built.All Cards Against Humanity Saves America recipients will get an illustrated map of the land, a certificate of our promise to fight the wall, some new cards, and a few other surprises."

Cards Against Humanity started in 2010 as a Kickstarter campaign that raised roughly 400 percent of its initial goal. The object of the card game is for players to outsmart each other by pairing a card with a word or phrase that forms a humorous or naughty sentence.
