It seems many people have given up using full stops in sentences and it’s all social media’s fault.
Linguists say it’s fairly obvious a sentence has come to an end in a text message, so full stops are now used less frequently to show the end of a sentence.
But 'Metro' reports that millennials are using them in a slightly different way, to show annoyance, sarcasm, and even aggression, making full stops a kind of emoticon. For example ‘fine.’ is seen as an angrier version of ‘fine’ without the dot. Dots are also used for emphasis, as in Best. Food. Ever.
While the full stop may be disappearing, the exclamation mark is becoming worked to death as in, “This is fantastic!!!!!!”
