When something occurs that makes everybody stop talking and pay attention to the situation. Usually funny and very embarrassing. Can happen in a large group or a small intimate setting. Usually has something to do with racism.
Here is a perfect example of random acts of silence

Background noise from party

Becky: This party is awesome.
Ray: Yeah its alright. Its a little dark in here though, if you know what I mean?
Becky: I could ask him to turn the lights up.
Ray: I mean there are a lot of coons in here.

When cooking, you grab a veritable cornucopia of things, and put them together for a recipe that ends up turning out to be amazing!!!
Stipulation: You may not have previously intended to make this recipe, it must be spur of the moment.
Dude, I just committed a random act of foodness. I defrosted some chicken in the fridge, but when it thawed, I realized it was pork chops. So, I randomly grabbed some sauce, cheese and peppers that happened to be in my fridge and baked it.
Excellence :)

When a dude suddenly does something extremely gay, like crossing his legs when he sits down. This has been known to destroy many good relationships.
My cousin's ex-girlfriend's hairdresser's nephew committed a random act of faggotry when he declined to go mountain climbing. His reason: "It'll ruin my manicure."

a silly or aggressively stupid act performed by your man for no reason other than to be an ass. This act can be either spontaneous or planned in advance.
While standing quietly in line at the cinema, her boyfriend unprovoked, impulsively grabbed her butt and yelled "oh, baby, your butt is getting so big", thus displaying yet another random act of assness.

A random act of designess, or RADness for short, is when you surf the web, find a good cause that needs some help with it’s identity, or promotional material (or anything else design related). Some appropriate design work that you believe will benefit the cause is done and together with an explanation, it is sent to them. A completely unsolicited way of helping a good cause just because you felt like it.
Hey, at the weekend I designed a funky new poster for that environmental group I came across on the web. I just really felt their cause was great but their promotional material wasn't. That's my first ever random act of designess (RADness), I wonder who I'll pick to do my next one for?!
