SoftlyWalking - I guess you cribbed the bit about "Finding out your mom has actually seen the film 2 girls 1 cup and knows exactly what it is" from some other site.
It's a sad state of affairs when a concerned parent becomes the target of a tiny group of vociferous net users with the combined IQ below that of an Amoeba, simply for expressing concern that a status on her daughter's Facebook page has changed to include some vile filth.
It's quite sad that anyone feels it "appropriate" or funny to have referred to the "2 girls 1 cup" video clip, and even sadder that there are some Facebook users complaining about the early closure of this advertising campaign with comments like "gutted" and "I miss all the funny status messages".
It is good riddance to some puerile comments. Whoever included the line(s) in the full knowledge of the target audience should not only get their P45, but be banned from advertising forever, and locked up for at least 5 years.
As for Coca-Cola, I can accept that in among perhaps 200 or more lines of "embarrassing" (crass toilet humour more like) messages, some will have slipped past, either because of the way they may have been presented, or just the monotony of having such a list to check.
Indeed one could argue that paying an advertising agency to manage the campaign, at perhaps 2 or more times the cost of the actual prizes, they could expect to have a professional managing it for them within the agency, who could be sure that it was suitable for the target audience.
Maybe they had some lad on a week's work experience who sneaked in an extra message "for a laugh". Whoever included it, I put more blame on the advertising agency than Coca-Cola, and it seems hardly surprising that whether Coca-Cola will ever use LMFM again is in question. Seems to me there has been a massive loss of trust in their ability to do a good job. Maybe other companies will pull their advertising, once they know this has gone public and Coca-Cola are under the spotlight for this error.
