1. The wrong guy has too much to drink. If he has one too many drinks on all too regular of a basis, he ends up making a fool of himself and everyone around him in the process.
Alcohol tends to reduce ones inhibitions. If a man (or woman, for that matter) has too many cocktails, they tend to get loud, obnoxious and irritating. They'll end up embarrassing themselves, and eventually, everyone nearby. He'll make boastful statements that aren't true, and make promises that he can't keep.
2. . The wrong guy flirts with everyone he meets. ( what is the exact mening of flirt with ..)He acts as if everyone in the bar is his personal dating black book??????.
When you flirt with someone, you make eye contact, you smile coyly, and you encourage their attention for a possible romantic encounter. A man's "black book" is a pocket-sized address book a bachelor keeps that contains women's names and phone numbers. (Not every man maintains one, but "little black book" has become synonymous with a single man's list of available women.)
3.This guy has handed his credit card to the bartender for round after round after round. . It's all play money(????) to him and he wants to be certain that everyone in the place knows it.
The man is showing off; he is paying for drinks on his credit card, and since he's not paying hard currency, it doesn't seem like "real" money to him. (He will think differently when he receives the credit card bill in the mail.) But he wants everyone in the bar to know that he's buying drinks for all, so that he looks like a "player" or a "big spender", that is, a successful guy that will attract the attention of the ladies.
