When you think a clean glass door or window is open and you fly into it like a sparrow would a glass window. Leaving you slightly dozy until you shake off the embarrassment.
"The new sliding door is super clean so don't go sparrowing through it!"

the classy duck face? Look off into the distance like you're slightly confused. keep your mouth somewhat ajar and your facial muscles slack. now get your photo taken. try to keep your eyes open wide.

The act of holding your breath after taking a toke on a spliff then as it becomes more difficult to keep the breath in, breathing in. Aiming to take at least 3 breaths before it becomes unbearable and you have to let it out.

Helps if you are standing to allow your lungs full capacity but be sure you have a friend who can catch you when you forget your legs are there!
Dude: Hey man, you know when you hold your breath after a toke, try to breath in when it gets hard to hold it!
Man: *tries* Woooah! Dude, I'm sparrowing!
