the act of giving a girl of only the Hottest body a rim-job. Only a girl of such beauty deserves a "dallat" (pronounced "doll + lot" - roll the two words together quickly to not make yourself sound like Zach). If given to a girl that does not deserve such an honor, male friends have the right to make fun of and or not be your friend anymore.
'Leedenheimer wanted to give Lisa and Murphy the dallat.'
Leedy- "That girl is so fine"
Trahan- "Ya, she is dallat material"
