I also loathe (and mentally knock IQ points off the poster) the following:
'The boy' if someone's talking about their son (you don't see 'the girl' half as much, I'm not sure why). This is usually alongside photos of the boy and we all know his name.
Actually no, wait: 'little miss' 
'Making Memories' - makes me want to turn my skin inside-out.
'No filter' - for a particularly nice photo of, eg, the weather. ALL smartphones now take gorgeous-looking photos, you do not NEED a sodding filter, it doesn't make you Ansell bloody Adams. Also, congratulations, you are somewhere there's actually some nice weather. Not jealous at all. 
'Over the rainbow bridge' - my older son finds this one so offensive in the face of genuine grief when our pet died that he didn't want me to mention it on FB in case someone I knew used it. Luckily they didn't. I know it's well meant but of all the crappy platitudes....
And finally (this is by no means an exhaustive list but I'm depressing myself now) those FB people who use a long series of pointless HASHTAGS to describe an event, day, mood, whatever. Rather than just bragging outright. I mean - just own it! If you've had a beautiful day then just say 'the sea is beautiful, the picnic was sublime, the children are happy for once, I'll remember this forever, my cat is also cute' but no, we get #vitaminsea #nofilter #nomnomnom #makingmemories #growinguptoofast #furbaby
You know who you are. Just stop it. People are not searching for hashtag nomnomnom. It is disgustingly twee.
