"dissolved" - In this context, it is a metaphor. His emotions were so strong that he either gave up his opinion, felt very sorry to have argued with her, or was emotionally overcome by his love for her. "got cleaned out" - In this context, it appears that something he ate caused his bowels to release their contents and he feels ill. "dibs on it" - this is a common but childish expression that means that someone has claimed first use of something. In this case, the "options".

1, dissolved right on the spot? I looked at her and almost dissolved right on the spot.( ”misunderstaning happened between them) I’m sorry, but this actually is rude. If we use this word in context, we “dissolve into laughter, (laugh and laugh because we cannot stop). this is sometimes offensive. 2, got cleaned out? Well, no dessert for you. Looks like you got cleaned out by something a little more......nutritious. This does not mean nutritious, it means that either you ate something that did not agree with your stomach so you had to go to the bathroom a lot, or it means that someone stole a lot of money or goods from you. 3, get bids on it? When someone in Hollywood options your work, it just means that they have got dibs on it. This example is correct.THX!
