I'm sure every single one of you has had a girl spill her drink near (or on) you at least once. If not, a) it will happen very soon, b) you've definitely had a girl bump into you. here's a nice roleplay routine to whip out in such a scenario, this one is for when a girl bumps into you, but I'm sure you can figure out how to transform it into a spilled drink routine:

HER: -bumps into you- "sorry"
YOU: no worries, but this is exactly why we can't have nice things

last week you knocked over our vase, wednsday you spilled coffee on our carpet, yesterday you fell UP the stairs... still dont know how you managed that... just face it,, your a clutz! (push her away lightly) . first thing tomorrow im baby proofing the house. plastic outlet covers, cabinet and drawer clasps, plastic covers on ALL sharp corners, the whole shabang. we're getting you a helmet too, but don't worry, you can take it off when we have friends and family over. but your keeping it on in bed! i dont care, saftey first! besides, im not attracted to superficial shit, so getting little spanky up wont be a problem for me,,,
HER: bla bla, (IGNORE whatever she says, dont answer her question, just keep going)
its whats on the inside that counts (easy transition to neil's "other then looks [and being clumsily cute], what do you have going for you)

or pretend she spilled her drink on you "OH MY GOD, twice in the past 3 minutes, [look around] SOMEBODY GET THIS GIRL A SIPPY CUP!"

feel free to post anything similar that could be used in this situation, don't get me wrong, i love using this and it gets great results, but it just happens so much that im starting to get a little bored of it
