The act of performing a mock "motoboat" (see "motoboat", the act of pushing one's face in between two
ample breasts, and rocking one's head side to side very rapidly while making a vigorous, lip-vibrating "
brrr" sound) in the air, as opposed to actually in between breasts, towards a deserving recipient.
Especially effective when targeted at a female
locked in conversation with another person and/or when drunkenly talking to her yourself.
"Man, I was so hammered last night I airboated
Barbara mid-convo. Couldn't
help myself, have you seen those meat
mellons?!"
