semi-endearment

A semi-endearment is a phrase used when puzzlement would be an acceptable outcome. It is ok to use a semi-endearment when you know a person well. But a little inappropriate as the semi-endearment can be a bit rude - but quite ok after an explaination.

Some examples of a semi-endearment are gruffalo or penny pockets. "oh here comes penny pockets" "here comes the gruffalo"

semicolon

The character ";" that you probably never use. It's used to fix comma splicing by separating two independent clauses while still including them in the same sentence. For example:
"I watch My Little Pony, Fluttershy is my favorite character."
can be corrected to
"I watch My Little Pony; Fluttershy is my favorite character."
People also use them in an attempt to sound smart when writing; almost in a condescending way; even if they don't know what they mean; and they never seen to realize how fabricated their writing looks with all the semicolons; and they probably started abusing them after reading classical novels."

English Teacher: "Well done on your 40 billionth argumentative essay, Harold. If I were you, I would put a semicolon there."

Harold: "What the snot is a semicolon?"
