If the jungler is applying pressure bot lane, taking dragons, counter jungling, killing mid lane repeatedly, etc.? Let it happen, because your fed ADC/Mid/Jungle will kill their fed top laner. Farm the couple jungle camps in your own jungle on top side when you can just to stay relevant, but stay on the top side and don't take his bot side camps (chances are he isn't farming his top side if he's applying pressure bot lane anyway).
If your jungler is not helping you, not applying pressure elsewhere, not counter jungling, and being toxic? Start taking his camps instead of laning. Leave your lane, let the enemy laner push it all the way to the nexus towers if you have to. Just take all the jungler's camps that you can, especially his buffs. The gold and experience from farming the jungle will help you stay relevant in the game and also make you not feed the enemy laner. It'll also take away options from your jungler, which forces them to either counter jungle, help you fight back in lane, or apply pressure elsewhere on the map.
