The act of putting a passed out/sleeping person on a skateboard and hurtling them underneath a squatting person as they defecate a series of short quick bursts of moist befoulment onto the moving soul beneath them. NOTE: In order to be granted 'series' status, there must be at least three seperate arse-discharges, otherwise it is only a 'meaty beneathy'.
Did you guys see Dave get a series of meaty beneathies last night at Kevin's party? He looked like a shit avalanche rolling down the driveway.
