It's an expression to say you've got to do something. To do your duty or when something reminds you to do your duty.
An simple example of this is:
When your you're chilling on a sofa and suddenly your baby starts crying and you gotta check it out, then you might say: Oops! Duty calls!!

A shooter game full of lag server bullshit, campers, noobs, noobtubers, 360 fanboys, spammers, little kids, and hackers. Join a match and you spawn and you already get killed by a chopper gunner killing everybody in the same spawn point. You steal someone's care package and later you receive a message by the "owner of the care package" cursing you out calling you a faggot because there was a gunship inside it. You also spawn and you get killed by a random tomahawk, and then you hear people screaming and getting orgasms over the mic because of how "epic that was". You slam your console and start going super saiyan in your room and next day you go on youtube and there you are on the featured video of "Epic Tomahawk Kill across the map". Next day you play search and destroy and while you are defusing the bomb 3-3 tied and suddenly you get knifed. You and everyone else look at the ending killcam and you are getting teabagged and raped and then knifed. You kick your console and it shuts down and you turn super saiyan 9000.
*Player gets noobtubed*
Player: What the f*ck man?! I hate noobtube campers! Ima kick your ass you f*cking cheater. Ima no scope your ass so you feel embarrased you fag!
*Player turns around a corner and no scopes and misses in front of his face and then he gets knifed*
Player:.............................i quit this sh*t. Call of duty is garbage! I swear this game is garbage!

Same shit. Different year.
I miss those times when a sequel in Call of Duty wasn't the same over-used garbage from 2007.

To be on bird duty is to be in charge of cooking the turkey for thanksgiving. Applies in other situations too.
- I gotta go. Do you think you can deal with the turkey ?
- But I thought that Tom was on bird duty this year.

Such a fickle thing.
"We are bound by a duty of care."

That an institution is allowed to have such an overpowering jurisdiction on the life events of an individual. An institution that will not follow up on the well being of general civilians, of children unencumbered by the proceedings of the system, or of those acting audaciously outside of their normal behaviours.
An institution claims to act on their "Duty of Care" only when it serves them to do so, only when it aids their motive.

What a member of the armed forces goes on, or becomes when they no longer feel the need for physical training. This is usually typical of a substandard individual, or 'turd' as they may be called from time to time. At times, some of these 'light duties' have a legitimate reason for not participating in physical training, however, most light duties will make themselves known at the most opportune time, ie, before a physical fitness test, or Company run. They usually will claim an ailment that is hard to diagnose, ie, back pain, knee pain, and the ultimate.. shin splints.
Guy #1: Man I really don't wanna run tomorrow. My favorite singer Adam Lambert is gonna be singing on Logo, and running will interfere with my duties as the Elton John Fan Club President.

Guy #2: No problem! Just go on Light Duty! That way, we can watch Adam Lambert all night long! Wanna make out?
