Usually you would say, 'it is bent'. That means it was straight, but no longer. If it's tilted up, you say it's bent up, or if it's the other direction, you say it's bent down. ('bent' is past participle of the verb 'bend') You can also say it is 'sticking up'/sticking down'. It's possible to say it's 'lifted up' as well. I wouldn't say it is screwed up. You will likely be misunderstood as 'screwed up' usually means 'it is broken/stuffed/no longer working'. If you use it in your sense, it means it is lifted up/down AND twisted as well.

Thank you for telling me this truth. I think he was saying that is broken. Because I said I don't understand, he said move back your feet. Showed me the bent one.

"screwed up" means any of wrecked, messed up, broken, not right in the head, having views that differ from your own.
