When a person working at an office takes a day of becuase he/she is qoute unqoute "sick". Usually they participate in an activity that is no where near their daily work related tasks.
The boyfriend effect is basically when your boyfriend comes to visit your place (or you go to visit his) and somehow your room ends up looking like absolute anarchy. The boyfriends presence somehow made the room go from completely organized to post apocalyptic…even though he literally didn’t do anything…and no one knows why.
“Sorry girl! My room’s a mess! I had it real clean this morning.”
