"Stop trying to suck up to me!"
"Will you back off? If I stop too quickly, I'll have to pull your head out of my ass!"
"Don't be such a kiss ass!"
"If you don't stop slobbering all over me, I'll need to put on my 'Helly Hansens'!"
Note: The 'Helly Hansen' company makes high quality rain gear.
I hope at least one of these is adequate for you.
