lose one's marbles

under one's hat

chew the fat

the life of the party

take a dip

pluck up

up one's alley

strike oil

keep one's nose to the grindstone

take the floor

up the creek

chapter and verse

push over

a feather in one's cap

walk on air

make short work of

a mile off

mop the floor with

go to pot

walking papers

have two strikes against

wash one's dirty linen in public

take the bull by the horns

cannon fodder

lean over backward

keep one's shirt on

waste one's breath

give it the old college try

for the hell of it

on one's person

a sight for sore eyes

watch A like a hawk

wear one's heart on one's sleeve

within spitting distance

spin one's wheels

kick oneself

wear the pants

crack the whip

on approval

hot button
