The period of time between Premier League games due to players going away on international duty.
There is, essentially, a lull due to internationals. Therefore 'Interlull'
"Oh man, this Interlull is so boring I think I might hack off one of my toes just for the want of something to do"
"I am spending my time during this Interlull praying that none of our players comes back with an injury or a dose of spina bifida or anything"
"The only way to cope with an Interlull is to go out and beat a water sheringham to death"
