Use goto for this 8-ball type of snippet:

on *:TEXT:$($iif(*gay* iswm $strip($1),$1)):#:{
  if (!%f) {
    set -u3 %f $true
    .describe # $rsom($strip($1-))
  }
}
alias -l rsom {
  goto $rand(1,10)
  :0 | return 0. no Asexual dont wanna sleep with real women or men
  :1 | return 1. no Straight thinking only of girls not how your body or any guys looks
  :2 | return 2. no Straight but like to compare your body to other men
  :3 | return 3. no Straight but think sometimes on what would it be like to be gây
  :4 | return 4. no Straight but do gây stuff when your bored, drunk, and/or hornÿ
  :5 | return 5. no Bi but dated more girls 
  :6 | return 6. no Bi but dated more boys
  :7 | return 7. Gây but do straight stuff when your bored, drunk, and/or hornÿ
  :8 | return 8. Gây but think sometimes on what would it be like to be straight.
  :9 | return 9. Gây but like to compare your looks to a women.
  :10 | return 10. Gây thinking only of man not how women bodies or styles look
}

I use an alias so I don't have to place the halt in each goto condition, along with a simple trigger flood protection and control codes stripped out.
