This happened this morning:

So a couple of my twitter friends and I were making jokes that Hazza and BooBear were in the next room making too much..erm…noise, and then the third tweet about “hoovers” came in. So we were wondering if “hoovers” meant anything, and we found results like this on multiple British slang dictionary websites:

So a “hoover” is a person who is good at giving blowjobs or just a blowjob itself.

And THEN Harry posted a picture of himself with obvious sex hair.

(That last bit is a joke, but come on, it’s probably true.)

So, in conclusion: Harry and Louis were having rough, kinky, loud sex next door to where Niall was trying to sleep, and to get them back for it he basically yelled at them for it on twitter to over 4 million people.
