Lyric discussion by a10dency2ask 

Actually "smoking a fag" is British slang for smoking a cigarette, and most liekly not a reference to "gay porn". I don't know how much meaning should be interpreted from this song, but my guess would be its about a guy who caught his girlfriend cheating. The "XU" part of the title suggests to me that he's tryign to get rid of something, since I guessed that X=get rid of and U= you.
