Life's a garden. Dig it.

Here's a quote from It's Always Sunny in Philadelphia.

quote = (
    "That's TA, TR's ex-girlfriend - this is classic TA. TR broke up with TA because MK said that "
    "she saw TA flirting with WT at a party OK, but she was only doing it to make TR jealous because, you know, "
    "she thought that TR secretly liked EH, but TR didn't like EH. It was all a bunch of bull."
)

This quote has numerous abbreviated names consisting of two capital letters. For example, "TR" stands for "Trey".

Given the following dictionary of abbreviation: full name mappings,

abbrevs = {
    "TA": "Tammy",
    "TR": "Trey",
    "MK": "Maureen Kinallen",
    "WT": "Walt Timby",
    "EH": "Erin Hannabry"
}

replace each abbreviation with the person's full name. Assume that some capitalized two-letter words like "OK", which are not abbreviated names, exist!

Expected result

newquote = (
    "That's Tammy, Trey's ex-girlfriend - this is classic Tammy. "
    "Trey broke up with Tammy because Maureen Kinallen said that she "
    "saw Tammy flirting with Walt Timby at a party OK, but she was only "
    "doing it to make Trey jealous because, you know, she thought that "
    "Trey secretly liked Erin Hannabry, but Trey didn't like Erin "
    "Hannabry. It was all a bunch of bull."
)
