Jean Marc XO is great vodka, expensive and hard to find though.
Are you looking for drinks that will get you drunk fast or put on a show or both?
Simple is a lot of times better, a lot of the complex drinks are very girl friendly and the sugar will get to you after you down several. This is not a rule, but a general guideline. Although if you haven't touched this type of thing much, it will be like juice/candy. Don't have more than a few in a night. Simple drinks will become more satisfying once you've become more experienced with different drinks.
You could try some bombs. These are drinks that are a pint of say beer then a shot of liquor dropped in and you drink it all quickly. Irish Car Bombs, Jager Bombs are alright (jager dropped in red bull). I forget what whiskey dropped in beer is called. Often these drinks are supposed to emulate a taste like dr pepper or even apple sauce.
Any shooters will work well.
You can't go wrong with Long Island Iced Teas and derivative drinks like Adios Motherfucker (called Code Blue some places), Tokyo Iced Tea, Long Beach Iced Tea, Los Angeles Iced Tea, etc. They have a lot of alcohol and (therefore) less sugary/fruity ingredients than most cocktails but still taste amazing if made right.
For showy drinks try something that is lit on fire like Flaming Lamborghini.
Don't ask the bartender for a random shot or "shot of anything." You'll probably get a shot poured from the spill mat or one of the disgusting but funny (at your expense) shots. Sometimes when douchy frat boys show up to my house or somebody's being an asshole I'll give them Cement Mixer shots (mostly Bailey's and a little lemon or lime juice). Tell them to mix it in their mouth before swallowing and the lemon juice curdles the cream in the Bailey's. Good for a laugh.
