When a guy is going down on a girl and she pees all over his face. Then, when he pulls away with a disgusted look on his face, she punches him in the nose. The mixture of piss and blood is the strawberry lemonade.

Gretchen: "I gave Bobby a strawberry lemonade."
Ricky: "Bobby what did you do last night?"

Ricky: "Oh, a strawberry lemonade! It happens."

A door wall is a sliding-glass door or patio door. The term is yet another example of banal Michigan vernacular, where in the residents latch on to company names, trademark names, marketing terms and product names from local companies. The terms become embedded in the local vocabulary and eventually become accepted as actual valid words and phrases. In this case the term comes from Wallside Windows in Taylor, MI (a large window manufacturer), where 'door wall' is their created word for sliding-glass door.
"Bob! John's gonna bring over them doorwalls from Wallsides on Tuesdee afternoon 'round two-thirty. Get 'er done!"
