Texting words like LOL and OMG may not be as cool as it once was.
A US study has found people using abbreviations or slang in texts sound 'stupid' to others.
Massey University linguistics expert Dr Arianna Berardi-Wiltshire says slang seems to have become less common.
She says changing tech may play a part - with phones now having full keyboards and predictive spelling.
"Young people are much more relationally aware than people were in the past - they know, quite often, when it's appropriate to use them."
