when there are a group of people passing around a weed-smoking device. ie: blunt, bowl, ect. a person who waits too long before hitting it and just sits and STALLS while everyone just wants them to freakin puff and pass, is "lunchboxing." they are a "lunchboxer."
Patient complaining: Man, I hate this—it's like a kick in the nuts.
Nurse reality checking: Your lunchbox vegetables are firmly out of scope here. It's just physiotherapy.
