Cheappuccino refers to any of the wide variety of flavored coffee drinks offered at convenience stores such as Circle K or 7 Eleven that can be purchased for less than half the price of a Starbucks cappuccino.

廉价咖啡指的是像Circle K或7 Eleven这样的便利店卖的各种口味的咖啡饮料，价钱还不到星巴克一杯卡布奇诺的一半。

Example: 

Let's stop by the Circle K for some cheappuccinos tonight. It's gonna be freaking cold, and all I've got is $1.25 in my wallet.

咱们今晚在Circle K停一下买几杯廉价咖啡吧。天气到时候会非常冷，而我钱包里只剩1.25美元了。
