Fleeting acquaintance
All-weather friend
Lead the pack
Fish or cut bait
Gilt-edged
To do more with less
Right down the middle
Take my word for it
40-sometimes
Last but not the least
Call it a dog
Pull my leg
Ego bath
Tough call
Rain check
Upper reaches
Off the shoulders
Off and running
Gold dust
Frugality fatigue
Red flag
Foregone conclusion
Call balls and strikes
