As a speaker of several languages, and an avid reader, I know that words are very important, more so, imo, the way words are put together. Even more important than the spoken word, are the written words. Of course, one needs to be aware of the social, cultural background words come from, but this is going way OT. In conclusion, the answer from me to the OP @mickle is: yes, we can, we should, it is better form not to use those terms. In saying that, please do not start to report instances of "pimp my bike, food/bike porn" on CC, because the above is only my personal opinion. Cheers!
