bottom up

Hi, everyone:

I'll bottom up my glass. You may drink as much of it as you like.

Is it ok to say "bottom up" in this sentence?

More explanation;

I know "bottoms up" is often used, but I'm not sure if it can be used in this way. If not, could you tell me a common expression to replace it?

Best wishes

No, In fact, I'm saying "the speaker wants to drink up his glass of liquor at one time, but he doesn't want to make it difficult for his guest,who may not be good at drinking liquor,to do like him". His words are said to make his guest comfortable drinking with him. In my country, If two persons are drinking liquor. If one says "cheers" and drinks up, the other doesn't drink up. It's considered to be not quite polite. So, the speaker says so in advance to avoid the embarassement and show politeness to his guest.

I've got it, Thank you, Yankee and Mister Micawber.

In fact, I'm trying to say the opposite (drink all，not a sip)

I think I'll use "drink up" instead.

In the UK, some slang expressions for drinking a shot of alcohol in one go are "to neck it", "down it in one" and "to slam it".
