look up any word, like slope:
 
1.
Spitting bullshit as a group or team. When just one person spitting bull isn't enough, it's time for a collab.
"We f**ked something up and don't want to tell the client, can you come over and we can collabullshit a reply that doesn't make us look bad?"

"Did you see this email from our vendor? That's some grade-A bullshit right there, must've been a collabullshitting session."
