My opinion:not sure what that MEANS EITHER
It means you're forcing your jungler to tank blue, use mana to damage it and wait for you to get into a good enough position to last hit the blue buff. Mid laners should be pushing their lanes to the enemy turret at 6:55-7:05 if they want the second blue without screwing up the ally jungler. I always keep the first 2 jungle buff timers to 7:10-7;15 and 12;20-12;25. I ain't going to wait for you ass to push your lane and screw up my timers so badly that I can't apply the maximum amount of pressure on the map when the enemy jungler is taking their buffs.
People almost never get ready for the second blue buff and waste the jungler's time. A jungler's time is precious. Even a few seconds of tanking blue for no reason may mean you falling behind in levels and gold.
Making me tank blue and making me back because I lost half my health is one of the most annoying things you can ever do to a jungler. I will tax your lane unquestionably if you force me into that position.
