Thank Science It's Friday. Used commonly by those who do not believe in God or of higher beings. Rather than saying it is Friday because of God's ways, TSIF says it is because of the laws of nature, and how once every 7 full rotations of the Earth the manmade term "Friday" applies for slightly over 24 hours.

Chris: Bro you know I don't believe in God I'm offended by that statement.
Sam: Oh shit I'm sorry, TSIF.

Get the TSIF mug.Taylor Swift. An alien eyed, crazy haired, big headed, small bodied, disproportionate, lying, cheating, rumor spreading, name calling, bashing, whiny, all around unattractive girl like creature. Makes many grammatical and literary errors in her songs such as “Love Story.” Romeo and Juliet die Taylor, ok? And he’s not talking slow, he’s talking low. She and MyCy are friends, which isn’t surprising as they both are delusional, certifiably insane, and are exes of the Jonas Brothers. Ruins an otherwise good day.
