HazzaBoo is the epic bromance between Louis Tomlinson and Harry Styles from One Direction. The combination comes from Harry's nickname Hazza and Louis' nickname Boo. They've been really close ever since X Factor 2010 when they got picked out for the group One Direction, along with three other boys, Niall Horan, Liam Payne and Zayn Malik. Now they're best friends and are currently living together in London. Louis has a girfriend but we all know that she's just a beard for Louis since he will go on to marrying Harry. Everybody is excited over their bromance and never ending love for eachother.
HazzaBoo is real. Just look..
Harry: Now kiss me you fool!
Louis: *starts snogging him on the couch*

and..

Question: Who would you like to marry?
Louis: Well, I'd marry you Harry. *Puts arm around him*
