Chat Lethal 

When finishing an opponent in Hearthstone, assume that every card costs 0 mana, opponent has no taunts or secrets, all spells and abilities can hit face, all minions have charge and immune to silence/freeze, and that arithmetically 2+2=9.

Retard #1: "OMFG KRIPP SO BAD MISSED LETHAL"
Retard #2: "wtf why hit senjin and not wrath+starfall face?"
Retard #3: "WOW LETHAL MISSED"
Guy #1: "he only had 3 mana... chat lethal"
Retard #4: "have you noticed children's pee smells like turnips?"

Lethal serious 

If something is so lethal or so serious the one word just doesnt cut it. It's like when you take 40 chats and are off your face and your on some buzz.

These chats are lethal serious

missing lethal

When a person is playing a childish card game having the perfect hand to kill his opponent, instead uses a different card to not kill the opponent and thus missing lethal.

I had the perfect cards to beat my opponent from winning this Blizzard Tournament, I mistakenly used Coldlight Oracle instead of using Pyroblast and Frostbolt the affect of using Coldlight Oracle caused me from winning the match and in turn missing lethal.

Lethal Lotus 

When a girl grabs onto a ceiling fan above a man who is laying down with a erect penis causing her to spin around on the penis. Then the girl will pull her self up and down making it a spining and up and down motion.
The sex postion was originaly invented in Connecticut and was called just the lotus until around 1980 when a girl died while in the postion from dysentary hence the "lethal" part of the name.
It is said not to be deadly, but some people say otherwise. Doctors tell people to advoid parttaking in the postion because if a penis is to big then it could rupture some inner organs. No one has repotadly died from it since the 1980 encounter.

Cindy- "Hey, want to do the 'lethal lotus'"?
Tim- "I dont know my doctor said it was kind of risky after that 1980 encounter"
Cindy- "It feels so good though"
Tim- "O.K lets do it!"
