sun's out guns out

When the winter is finally over and it is just starting to get warm, you wear your short sleeve polo shirts to work rather than a long sleeve. This particularly applies to musclehead italians from the tri-state area who have been dying to show off their bi's and tri's all winter.

-"hey Paul, nice shirt-short sleeves already??"
-"yep. sun's out guns out"
-"but Paul, it's mid April?"
-what do you mean???

Sun's out, guns out 

A phrase used to indicate the arrival of a buzzsaw, especially when said buzzsaw is the topic of a rude discussion.

"Shut up guys, sun's out guns out" Mike said as Buzzsaw walked into the room
