How to tilt your laner
Leave him to be 2v1'd and kept from snowballing even though you easily win the 2v2 and he's the only lane with snowball potential at the time; camp for a feeding lane with 0 kill potential instead or afk farm.
Invade 1v2 or 1v3 when your laners are basing or shoved in; ignore easy gank opportunity in said lane immediately before doing said 1v2 or 1v3 invade of enemy jg.
Ignore multiple pings, position of wave, level advantages/disadvantages, and cd's to force a 1v1 vs enemy laner. Die to said laner - giving them free doubles - then flame your laner.
Recall 2ft away from an enemy laner that is one auto and a basic ability from dead while you are very healthy. Make sure your laner is too low to finish off their opponent by themselves without merely trading kills too. Then harass them as they get chunked out of lane again because of option 1 on the list while you sit afk farming and exert no pressure anywhere on map.
Lose every 4v3 and every objective across the map.
Flame your laner for not teleporting, but provide no tp wards.
Run to lane and steal their farm just before they get to lane under the premise of "last hitting'. Be the wave is set to push to their opponent and give that person a freeze.
Lose every teamfight they are not in, win every teamfight they are a part of, do not every compliment them, and make sure to tell them they never do anything for the team.
Get them to help you deal with the enemy counter-jungling, then once they commit, leave them 1v2 or 2v3 when you are nearly full hp.
Refuse to engage as the primary engage person on your team vs a heavy poke comp.
Engage a fight, bait out your teammate's tp, then run away and leave them to die 1v5 because they got off a great tp flank... only to have their team ditch the engage for no reason after it's too late to cancel tp.
Whenever you could save your teammate and grab an easy kill, chase an enemy you have 0 chance of catching and killing instead.
Whenever you could counter-gank and save your laner, get a double kill, and THEN go do another jg camp... do the jg camp instead even though they are the same distance away. Farm more important than killing 2 enemies, saving your teammate, and stealing the enemy jungler's farm while he's dead.
Randomly and repeatedly ping a non-existent enemy gank incoming to your teammate's lane.
Refuse to counter-gank when you are there, full hp and sums, and could clearly get a 2 for 0 and the enemy jg's double buffs. Instead walk across the entire map to afk farm or gank for a lane with 0 kill pressure that is feeding. Bonus... die during said gank.
Just a few things I see way too often which tilt me. What tilts you as a laner?
