A shortened way of saying "Thank god it's Friday." Used by students to express their overwhelming joy knowing that they don't have school tomorrow, meaning they can sleep in and they can procrastinate until Sunday night to do their homework.

Tear gas is fantastic.

When HK citizens smoke too much of expired tear gas during peaceful "riots" , they get addicted to the tear gas with cyanide and say this.
Protesters: We are already leaving! Why are the popo still firing tear gas at us? (Not being able to leave because of the shutdown of MTR stations near the protesting site)
Andy: (addicted to tear gas due to unreasonable firing of the popo) TGIF!!!!
