I ping once when i start.
I ping once again when its half way.
Then it belongs to 
And then 2 minutes later they scream at you for having blue on jungle 
i ping assist me, if they dont i'll take it =D shy needs it
ice cream, you fool just eat it
My biggest peeve though when I midlane is a jungle trying to give blue either:
Right when I need to back and not backing now gives advantage to their midlaner (I just back anyway and tell jungle to take it if he can't wait)
When there is a wave at my turret, sorry, but losing creeps for no reason isn't a good idea.
For those reason I usually tell my mid when they are getting blue and let them fast push a wave so that they lose nothing and gain blue.

When your jungler is trying to force feed you blue buff at an inopportune time:
