Holly Harley posted a clip of her boyfriend making a brew, captioning it “the worst video in the world.”
Ms Harley’s boyfriend can be seen pouring sugar into a mug followed by hot water and then milk before finally adding the tea bag.
She later commented: “I’m sorry to report that he drank it (after reintroducing the teabag for a bit longer): ‘I wasn’t going to waste it!’ Needless to say, it was ‘pretty bad’.”
Thousands have commented on the video, calling the method “horrible”, “anarchy” and “utter depravity”.
Nadine Morgan: “He put sugar and milk in and made sugarmilkhotwater. THEN put the tea bag in. IT’S ANARCHY.”
Another person wrote: “This is horrible. Please say that was immediately poured down the sink.”
Chip Collis also said: “Even I, a lifelong coffee drinker from the Midwest, recognize the utter depravity involved in making tea-tinctured sugar milk.
“Thoughts and prayers in your time of trial. I hope you can get through this together.”
Some even called on Ms Harley to dump her boyfriend due to his questionable tea-making technique.
One person wrote: “I don’t know you, lady, but you need to throw the whole boyfriend away and that cup of whatever that is.”
Another said: “Surely you mean ‘ex-boyfriend?’”
Nanjala Nyabola also commented: “There are some real monsters in this world. They walk among us.”
