Clock the T

Seems to be used more in the gay community, more specifically in the gay black community.

T is short for "the truth," so clocking the T means

1) to tell the truth, the whole truth, and nothing but the truth, without embellishments, without edits, and without apology.

2) to state your own personal opinion about any person, place, thing, or situation, again without embellishments, edits, or apology.

In layman's terms, Clocking the T is synonymous with "keeping it real." It can also be used for gossip.
Quaadir Howard from youtube (username Timaya) giving his opinion on Lady Gaga (paraphrased)-
"I don't too much care for her. People are giving her praises but I'm not impressed. Her videos and perfornances hardly make sense with her songs. She's vulgar and over the top just for the sake of getting attention and fame. That is my opinion and you don't have to like it. If she gave me what i needed, I would have given her kudos, but she didn't and I'm going to clock the T where the T needs to be clocked, mmkay sweetheart?"

Adam - "Watch this dance move!" *starts dancing horribly* "So how did you like my dancing, Keith?"
Keith - "You really don't need to be dancing. You look like a retarded flamingo trying to find a mate."
Adam - "that's not very nice"
Keith - "Well if you ask for my opinion, ms thing, I'm going to clock the T on that ass. how you doin."

alarm clock

Probably the most annoying thing on a Monday morning, or any morning for that matter, but very useful when you need to wake up early or at a certain time. Usually have very high pitched tones so you will be so annoyed that you'll get out of bed to turn the damn thing off.
Person One: I need to wake up early! I should tell my mom to wake me up.

Person Two: You should just set an alarm clock. It's a more annoying sound which most likely will get you out of bed faster to turn it off.

Person One: Good idea!

Rape Clock

Rape Clock is a meme from 4chan's /b/.

It's a picture of Silent Hill 2's Pyramid Head drawn next to a large clock that says "rape" at every time slot with the hands almost together at one of the "rape"s.

Pyramid Head has one hand up in surprise exclaiming, "Good Heavens, just look at the time!"
"The Rape Clock says I'm late for a 'meeting' in the park. And by meeting, I mean rape."

Clock Milker

Someone who shows up to work and is completely unproductive, and spends countless hours looking up new definitions on urbandictionary.com.
"Greg" is a clock milker because he comes in everyday and spend hours 6-8 just surfing the web, still pulling the wool over his bosses eyes and taking home his payheck.
