what does this sentence mean?

Yesterday I had an ESL class. My teacher was 45 years old American native speaker. He was asking everyone's opinion on their weekends. I asked him what he normally did on his weekends. He told me that he drinks 2 glasses of anxiety. I did not understand him. I came back home and asked my older brother what that sentence meant. He told me that it meant "he is a loser". I am totally confused. Any comments?

Thanks.

He's joking, or, in southern vernacular, "pulling your leg (or chain)." He's saying that his weekends are full of anxiety. One can only surmise the reason. One good guess would be his wife's "honey-do" list. :D

Earle is correct, your instructor was joking with you. It seems to me that it's in pretty poor taste to be joking like that with people he knows are likely to not understand or misunderstand him. At the very least he should have made it clear he was joking and explained what the joke meant. Your brother may be right that this guy is a loser.
