🎬Tuesday afternoon at the office, Sarah is staring at a blank screen while Mark is hiding in the breakroom.
Mark
David's on a mighty tear today. Just ripped into Jim for like ten mins.
Sarah
Glad I'm ghosting him until lunch then.

Mark uses 'mighty' as an informal adverb meaning 'extremely' to describe David's anger. He uses the idiom 'on a tear' to describe a period of intense activity or aggression. Sarah responds by saying she is 'ghosting' (intentionally ignoring) her boss to avoid becoming the next target.
